You will break the standard. It's built to use four twisted pairs. The moment
you run any other AC through any pairs you'll break the standard. There is a
magnetic field which you will mess up.
What happens varies with the conditions, but you will for sure not help. The
standard thing to do is to pull another pair. Or put a switch at the other
end.
Ethernet is built to be very resilient, but we are talking about high
frequency signals running through the cable. We are not talking about some 9V
DC running through it. For example if you are running Gigabit then just
running a tight 90 degree turn will be outside the spec.
