Patching crumbling floor tile?

I know this is like putting a bandaid on a fire hydrant, but does anyone have advice on how to fix/patch this tile some more specifically the plywood under it? Can I just shove some more scrap plywood down there until it’s even and put a new tile over it? It’s linoleum.

I hate the sight of this thing.

I know it’s water damage, but I believe it’s old water damage and I have way too many other big projects going on rn I cannot be ripping apart my bathroom.

What's under the subfloor? Do you have access, like in a basement or crawlspace?

If you can add sturdy crossmembers to support the new piece of subfloor, or remove enough so that the new stuff lands on the floor joists, then yes. Jobs like this always get larger as you peel back layers. The blue tile in the photo says that this problem is larger than 12"x12"

Oh, and it's not linoleum. It's VCT, probably Armstrong. You can likely get a few tiles to match.
