Should be no problem, as long as there is either room in the existing clamp,
or a knockout to add a new clamp for the new wire.  

Also make sure you run a safety ground in some fashion (assuming your new
fixtures are metal).  Your old fixtures may or may not have ground wires in
them, if not you'll want to find another way to do it.
