Wood – replace a hardwood floor board without replacing the entire floor
floorhardwood
I have a piece of floor that expanded and is popping up due to some water damage (attached photo).
Is it possible to just take out the piece and trim it down to make it fit? Or would I need to replace the entire floor?

You definitely do not need to replace the entire floor; the board is a different question. Typically repairing a hardwood floor involves splitting and removing one board before you can remove the adjacent ones from the tongue and grooves. Later you can replace the damaged board with the same species, or a leftover piece. (Occasionally you can pilfer one from inside a closet or remodeled space.)
That looks like a floating floor though, so you may be able to carefully prod that piece up and out. Possibly even undercut it a bit with a really fine trim saw or oscilating tool if you can get the entire side up.
Once you do have it out replacement is fairly straightforward. Cut away the bottom side of the groove and run a thin bead of adhesive along the adjacent tongue, then slide the board into place at an angle inserting the tongue into the place then pressing the half-groove down into the glue.
Old houses have 3/4'' thick wood planks as subfloor, not 8x4 sheets of plywood like today's houses, so I would say that it's ok to consider your hardwood floor the subfloor. That's if you're putting another wood floor on top.
However, for the purpose of tiling you need an additional layer of plywood to reduce deflection that will cause the grout to crack eventually. And on top of that you would install your cement board. The cement board itself provides no structural support and is only used as a decoupling between a wood subfloor and the tiles, so the lateral movement of the wood is not going to cause the tiles to pull up. You can always use a durock membrane to reduce thickness, but you still need a floor that will not deflect.
If you really want to do this right you would take out the old floor down to the joist and install some OSB and then do what you want...
I really doubt you can sand your floors. Some engineered floors can be but this is a very small percent. And this would be a diy because pros won't want to be responsible for the thin top layer sanding through.
One of the things I have found with engineered hardwood is the clear coat varies drastically from different types. I have tested a lot and some scratch by pushing a penny across it and others I have had to stab full force with a screwdriver. I am guessing yours scratches with a penny.
So the only cost effective thing that would definitely help would be to add a couple layers of poly. You may need several layers.
