The outlet for my range hood was misplaced. It needs to be 4 inches to the side. I can make the junction and move the wiring to the new location but I really don't want to have the empty plate exposed.
The wire is not long enough to reach the required location, so I will make a junction in the existing box, and add a new box at the correct location.
Is there any acceptable circumstance where I could tile over the "old" in-wall junction box?
I'm guessing not, but I figured I'd ask.
EDIT: I should clarify, based on the answers below… I know for a fact that this outlet is the only line on this entire circuit, all the way back to the panel. I am asking explicitly if there is any way to acceptably splice the wiring without exposing a junction box.

You cannot cover any junction box that still has live wires in it. Your best bet is to either remove the box all together or just put a cover plate on it. Your other option is to run a new circuit to the new box and de-energize the circuit to the old box and mark the source wires as "NOT IN USE" at your panel in which case I believe you could cover it over.
If there are live wires in the box, sooner or later you will need to get to the box again, which you can't do if you've covered it over! You'll thank yourself later (as will any future home owner).
