Because the unit charged, it can activate even if it's no longer within 1" of an enemy unit. It can do everything it normally could in the fight phase, but can only attack units it declared a charge against. If there is no valid target to attack, it will just Pile In and Consolidate as normal without making any attacks.
This is why multi-target charging is important. Even if you don't think you'll make it into the other unit(s) with your charge roll, you might be able to pile into them to attack them.
