I would think that if you're lucky you could put 5V on the brown pair,
which would enable you to move said wall wart.

You could also theoretically mangle your cable to use both sets of
pairs, and get an extra jack where you need it.

Third option: does one of the boxes run Linux? Stick an extra NIC in it
and do bridging for your other box.
