While I would not necessarily consider this canon, in Predator 2 we see a Xenomorph skull being kept in the Predator ship as a trophy. The bleached white skull could not exist if the Xenomorphs possessed only an exoskeleton. Mind you as stated it was a cameo appearance in an outside franchise, and thus could not be considered canon. I am also curious about where this information on the endoskelton comes from. Based on what Legion says it makes sense for them to have an endoskeleton, but I have never heard any official info regarding this.
