That will work, especially for short runs. The caveat is that
you want to keep pairs together.

That's true. I should have said the colors are immaterial, but you want to keep
the twisted pairs together. Ie, the TX pair should be twisted and the RX pair
should be twisted. On newer wiring this is easier as the pairs are the same
color, with one of the two wires being striped.
