Probably not. If the head exploded, there would have been blood and tissure all over the place, not just a missing head. Rodent Pro is notorious for poorly packaging the rats so that the dry ice sits directly on them in the box. I have had rats arrive headless and some where the dry ice just partly cracked the skin and after warming up the head was already flopping around.
