Irrigation Wiring
I have 4 red wires going to 4 zones. My question, could I combine 2 zones together, making instead 4 total zones to make 2 total zones by simply joining 2 red wires together. Making say, zones 1&2 come on at the same time. My pump cycles on and off every 30 seconds or so, yes there is a 20 gal tank on the system and one horse submersible.

You should be able to, yes. The only concern would be if the timer doesn't provide enough power to turn on two solenoids at the same time. I've admittedly never tried this, but it should work just fine.

With many controllers it's also easy to simply program more than one zone to come on at the same time.

There might not be enough water pressure or volume to operate two zones' worth of sprinkler heads at the same time.
You will probably have water coming out of each head but the surface coverage would be much smaller.
Volume problems would be due to too small pipes in the shared portion of the plumbing (also contributes to pressure loss), or you might overdraw the well causing air or even dirt to be drawn up by the pump.
Having enough water pressure and volume/delivery was the original reason for having more than one zone in the first place.
