The TCP Listen VI is, as far as I'm aware, a wrapper for the TCP Create Listener and TCP Wait On Listener functions.  Chances are that the Listener functions were there first and the Listen VI was added in a later LabVIEW version for convenience.

The "Multiple Connections - Server.vi" example shows how you might use the Create Listener and Wait on Listener functions.  You could do this with TCP Listen, but it would be less clear and doesn't offer any way to close the Listener refnum.
