Why would you want to do that? Unresolved DNS names would cause the listener to fail as no valid adderss would exist upon which to listen for connections.

No, the listener would have no valid address upon which to listen. Your users would likely receive a "TNS-12541: no listener" error.

Of course you could test this on your own and post the results, as none of us has a listener configuration to be tampered with.
