Yes it can. I've done two or three. The cord simply goes into the motor housing then splits off and goes two directions. All you do is unsolder the cord where it's soldered to the motor wires and remove it.
Some have a plastic stress relief that holds the cord and others have a weird knot just inside the housing to prevent the wire from pulling on the motor wires.
Once you get the motor apart, clean it well but carefully. Clean the commutator so the brushes get good contact, it's a good time to replace them if needed. Clean up the bearing or bushing area as well. And if there are no external lube holes this is a good time to lube them. Most have some sort of lube, grease or oil. You just gotta figure out how to get it in.
After all that you put it back together and plug it in.
