It depends on how the switch and receptacle are wired.

If the feed goes to the switch first no problem.

If the feed goes to the receptacle first and a switch loop was run over to the switch then you do not have a neutral in the switch box.

There is hope even if the power goes to the receptacle first. If you are going to install the ceiling light and have no need for a switched receptacle you should be fine. Simply re wire the receptacle location to make what was previously the hot and return from the switch into a hot and neutral to the switch and wire the receptacle hot all the time.
