For the clear answer, 1" thick plywood will be vary hard to get up if it has been glued down, I would tile over what you have and live with a little diff. in height. I don't like that answer either but I think ripping into it will be a nightmare.
I was just triing to get enough information before giving you my answer.
Let us know what you end up doing and how it goes.

In the game of "Why Don't You -- Yes But," players begin by bemoaning a problem and inviting others to suggest solutions, all of which will be shot down. The real object, Berne writes, is "to demonstrate that no one can give them an acceptable suggestion."

. . .but this one does not quite fit this profile.

Shea, the subfloor is the layer of wood that is on top of the floor joists. You can remove all wood above that, then replace it with hardwood flooring; or, replace it with plywood if you are going to use linoleum or vinyl or carpet; or, replace it with concrete (Hardie) backer board if you are going to use ceramic or stone for your final floor.

It is difficult to tell by seeing the picture..
you should try to remove the top layer ..
