I would have an issue with non-Christians holding the Eucharist, because it wouldn't have meaning to them. However Christians hold the Tanakh to be scripture, so some, but not all by any stretch, might celebrate Passover because of the command in Exodus. Since they won't have Rabbinical tradition to draw on, it would probably take a different form. Especially since we associate the Last Supper with Passover.
