Xykon seems to think that it could at least be a problem, or else there would be no need for him to command MitD to spit it out afterwards. Since there's a wide range of things that MitD could be, having that ability doesn't seem to unreasonable an assumption, at least for these purposes.
And even if he cant actually digest the phylactery, Xykon probably doesn't want to regenerate inside the MITD's stomach any more than, say, that of a sea serpent.
