The simplest answer to your "Can I run master and slave on the same machine" is "Yes". The challenging part of the question is "Why?"
The subject line seems to hint that you are considering running a master and a slave on the same machine. It certainly can be done. Whether it should be done depends on your reason for wanting to use a slave. The Jenkins master can run multiple jobs in parallel so long as you allow have enough executors defined on the master node to host your parallel jobs. If the master machine has enough compute power to perform all the parallel jobs, then executing all the jobs on the master node is simpler because it is easier to administer one machine (the master) than two machines (the master and the slave). If the master machine does not have enough compute power to perform all the parallel jobs, then additional computers can be added as slave nodes to add compute power. Another use of master and slave is when different configurations are needed. For example, I have a master node that is 64 bit Linux and slave nodes for 32 bit Linux, 32 bit Windows, and 64 bit Windows. I couldn't run that configuration without master and slave setups. I believe others have used a slave configuration to create a separate configuration even on the same machine. That is not a technique I've used, but I've considered it, possibly using a slave running in a chroot environment on a Linux machine to simulate a different configuration without actually running on a different machine. It is also possible to run a master and a slave on the same machine simply by configuring the slave node to use a different home directory than the master node. I'm not sure why you would do that, but it can be done.
