You CAN have two separate clusters with same name and configuration. Separation of the clusters is just a matter of defining seed nodes properly. That being said, it doesn't mean you SHOULD have clusters with same name. We usually run same cluster name when testing on test/stage cluster and deploying same hardware and configuration as a "production" cluster but they are always in different physical networks and/or VPCs. Just make sure nodes from one cluster can't see nodes from a seconds one and you are fine.
