They couldn't point to a DNAME, but they could point to a target that would resolve through a DNAME-using resolution. To my knowledge there is no explicit prohibition, but if you asked in the right way (such as without DO set) you'd get a CNAME synthesized, which would mean that the thing would break sometimes and not other times. Seems even less good for that reason.
