The name "AR15" can only be used by Colt and companies which licence their product from Colt. Other manufacturers usually use some sort of variation for the sake of legality, such as DPMS with "A15", "AP4", etc., DoubleStar with "STAR 15", and so forth. So, from that perspective, only a Colt or Colt licenced product technically qualifies as an AR15. But, from a legal perspective (as far as so-called assault weapons ban laws go), most anything designed/patterned after the AR15 will qualify, including gas piston upper systems, receivers made from castings (such as Norinco, Hesse/Blackthorn, etc.), and different calibre rifles.
