If I don't have any fish in my tank, can I just leave the light on all the time so my coral are constantly photosynthesizing? Or do they need a night cycle too?

They need a rest period.

+1 Not only do the corals need a rest period, but there are many critters that only come out & feed in total darkness, so they need their time as well.

So complete darkness?

Yes....
My moonlights go off at 11:30pm, and the dawn/dusks don't come back on until 1:00pm, so mine goes 13.5hrs without light.

I don't have a timer or any dawn/ dusk lighting. Is there any concern about going from no light to full light?

No, you're fine without dawn/dusk or moonlights, but I would pick up a $10-$15 timer so your tank is on a regular light schedule.
