If by some form of link you mean ethernet and TCP/IP, then yes. This would simply be a matter of setting the ROS_MASTER_URI and ROS_HOSTNAME / ROS_IP variables correctly. See ROS/Tutorials/MultipleMachines for more info.
Also, be sure to have a working network before attempting to do anything more than simple tests (diagnosing network issues can become quite complex if you're running a full application). See ROS/NetworkSetup and make sure all tests pass and return valid results.
An alternative to a single master would be to run a multi-master setup. This is much more involved though, and if all your CPUs are on the same physical network, not wireless and connected by reliable links, a single master setup probably makes more sense. In any case, see wiki/sig/Multimaster, multimaster_fkie (just one example) and rocon (robotics in concert) for a start.
