The fact that Pluto suffers violent tidal effects with it’s 'moon' Charon is enough to explain why ancient impact sites have been wiped.

Are you suggesting that tidal forces from gravitational interactions with its moon creates enough frictional heat to cause volcanism there? Because this does appear to be the case with other planets' moons.
