Yes, it can. I'd say 95% of the stuff can be done with Linux. If
you want high-end solutions, you have to go with Cisco. For
example, you cannot use it as a backbone router for ATM or Frame
Relay network. ATM/FR support in Linux is not mature enough for
backbone use.
I used to have an ISP in Russia totally on Linux. Linux routers
(using flash disks, Cronyx sync serial cards etc) and Linux
servers.

The main "limitation" in case of LEAF, or any "hand-made" Linux
solution, is that there is nobody to blame if it doesn't work. In
case of Cisco, I just say "it doesn't work, blame Cisco" (and it
does fail quite often). In case a Linux system fails, I get my
hands dirty and try to fix it. :-) If you're not sure you can
fix it, then its better to secure support from somebody else.
Linux can, and will work for business use. And it also will give
you flexibility which no proprietary device can give.
As an example, here is an uptime of a server which does routing
for 100+ workstations/devices (between VLANs and network
segments):
$ uptime
11:00pm up 481 days, 20:37, 3 users, load average: 0.54, 0.32, 0.29
$ /sbin/arp -a -n | wc
116 806 5945
We were going to move routing to our Cisco Catalyst 6000 ($30k+
piece of hardware), but were unable to configure routing the way
it is done by a Linux box - it just lacks the flexibility
required (I admit that our routing setup is quite weird).
Just my $0.02.
