You can but only if your mac does not include an internal optical drive.

This guide I have written myself so hope you like it. It is below.
Installing Mac OS X from a USB flash drive
This guide will show you how to create a bootable USB flash drive to install
Mac OS X. Here are the prerequisites.
A USB flash drive that's at least 8 GB in size. The installer and other files
take up at least this space.
A program called DiskMakerX previously known as Lion Disk Maker available from
http://liondiskmaker.com/
The latest version of a supported operating system (Lion, Mountain Lion or
Mavericks) available from the Mac App Store.
Instructions
1. Download the above two apps listed in the prerequisites.
Important!
After downloading the latest supported operating system from the Mac App Store
the installer opens automatically. Do not proceed since the file will be erased
upon the reboot. Instead, press command-q at the first screen of the installer
where the continue button has the keyboard focus.
2. Open the DiskMakerX disk image in the finder. It should then appear in the
image browser. You can accomplish this by highlighting the dmg file with just
arrow keys and press command-o for open.
3. For reasons of better accessibility I then switch to list view with
command-2. Copy the only .app file in there and paste into your applications
folder. This is accomplished with command-c for copy, command-shift-a to open
the Applications folder and command-v to paste. Once copied close all Finder
windows with command-w so you're at the desktop and eject the disk image by
first highlighting it with just arrow keys and press command-e for eject.
5. Connect the USB flash drive to your mac before beginning the next step.
6. Open the DiskMakerX which should now be located in your applications folder.
7. When prompted that Safari has downloaded this application from the web
vo-arrow to the open button and press vo-space to activate. With QuickNav
enabled with left-right arrows together you can simply navigate to the open
button with left or right arrow keys then press up-down arrows together to
activate.
Note
By VO throughout this guide I am talking about the VoiceOver keys which are
control-option.
8. Follow the instructions on the screen. For example when choosing the
operating system click either Lion, Mountain Lion or Mavericks button.
9. When it comes to the USB flash drive part choose to have it create as an 8
GB flash drive. You will be warned that all data will be erased so make sure
your flash drive is backed up somewhere.
Note
If you have previously made a bootable USB flash drive you can update the
volume here by clicking the appropriate button.
Tip
Since the application uses appropriate options as default buttons in most
cases, pressing return will be enough to move on to the next screen.
10. The preparation and copying will eventually begin. Do not worry about any
busy busy busy messages or that the app has no windows. It is just doing its
work behind the scenes. Please enter any credentials when prompted. VoiceOver
makes a clicking type sound when in password text fields.
11. When all finished, you are invited to either open Start-up Disk preferences
so you can quickly change to the newly created or updated bootable USB flash
drive and test your creations. You are also invited to make a donation to the
developers which is in fact the default button so pressing return will open
your browser allowing you to make such a donation. Finally there is a quit
button which does what it says; quit the application. Let's then click the open
Start-up Disk Preferences button.
12. Interact with the possible start-up disks scroll area, choose your bootable
USB Flash Drive by selecting the appropriate radio buttons, stop interacting
with the scroll area and click restart button. To interact and stop interact
with VoiceOver do one of the following:
A. Press vo-shift-down arrow to interact; vo-shift-up arrow to stop interacting.
B. Press down-right arrows to interact; down-left arrows to stop interacting.
This is assuming QuickNav is enabled with left-right arrows.
13. Click restart button again to confirm you want to restart the computer.
14. Your USB flash drive should now boot up and eventually display the Mac OS X
Utilities with the applications table having keyboard focus. How long it takes
depends on your USB flash drive. On my Verbatim 64 GB USB flash drive it takes
about thirty seconds.
15. To enable the whole operation to talk and output to Braille if you have
such facilities requires starting VoiceOver. To do this press command-F5. You
may hear a different voice than what you're used to. This is because in effect
a temporary copy of VoiceOver used for installation and other purposes is
running and so the voice is set to Fred which runs on even older hardware. If
using Braille only USB refreshable Braille displays will be supported at this
time.
16. To manage your disks including partitioning, select Disk Utility and click
continue button.
Important!
Should you wish to repartition your disk, please be aware all data previously
stored on the disk will be erased. Make sure you have a disk backup somewhere.
17. Let's for example structure the disk so you have one big partition. To do
this:
a. Interact with the disks table and choose the topmost column which is your
entire disk and not just your start-up partition.
b. Stop interacting with the disks table, click the partition tab to select it,
choose 1 from the partition layout pop-up button and click apply button.
Interacting with a pop-up button involves activating the item with either
vo-space (up-down arrows if QuickNav is enabled), space or return.
Note
The current option allows you to manage the partitions on the disk without
losing data.
18. Confirm you wish to layout the partition this way by clicking the partition
button. It will then go away and do its thing. This should take a matter of
seconds. You will even see it format the disk with the appropriate file system
and disk label which you can also choose before applying the new layout.
19. When all finished quit Disk Utility with command-q and return to the OS X
Utilities screen.
20. Now it's time to install Mac OS X from the bootable USB flash drive. So
interact with the applications table, choose Install Mac OS X, stop interacting
with the applications table and click continue button.
21. It is now a matter of just following the on screen instructions.
Note
At the final step of the installer before it does its work, VoiceOver appears
to lose focus. You will know this as attempting to navigate will only result in
a ding. To get around this press VO-F2-F2 to open the Window Chooser menu, down
arrow to the Installer and press return. You should now be able to select the
disk you wish to install OS X on and click the install button.
Important!
At the preparing to install screen, when it says about a second remaining and
it's at 99.9% the installer appears to hang. Do not panic and certainly do not
do a thing. Just walk away, grab your favourite refreshments and before you
know it the mac will suddenly boot to the installer now stored on the hard disk.
I hope you find this guide to be of use. Any comments good or bad will be very
welcome. Thank you and happy reading!
