There's no problem pushing the piston back. It will push fluid back into the reservoir but it won't damage the abs.
To be honest, once they seize they are usually on their way out and need replacing or refurbing.
Your only chance is to push the piston almost all the way out, lift the dust cover on the piston and clean out any crap and muck, then push the piston back in and check that it operates smoothly.
Chances are the piston has corroded and this is why it has seized or is seizing.

This is what I did to my rears and found bad corrosion and knackered seals.
I push the piston out and clean it up with some emery cloth, greased and pushed it back in.
It sorted the problem for now, but a new calliper will be need as it will happen again.

If it looks anything like this, good luck with pushing it back in...

Thought I'd add an update;
I stripped my front brakes down yesterday to see what was occuring.
I found the pistons to be OK but a lot of grime around the pads which were very stiff to slide. Pads were getting low and looked to have seen better days.
Stripped the calipers right down and gave them a good clean. New pads boths side with some fresh copper slip and all seems to be great.
Looks like brakes just needed a bit of TLC.

I say this on every 'seized' caliper thread, sooner or later more 'later' they will just seize again.
I freed off my front's twice the second time one of them was in the state of no return and i had to buy another, the rears are worse.
So far I've replaced all 4 so far so good.
