Can my Tirant 45 be used on the 300 Blackout?

Yes.  Subs only.

What threads are on your 300BLK?  Does AAC make a piston for those threads?

If there's a piston in .625-28 then start launching 220gr subs thru it. I don't recall seeing one though.

Good luck OP.

AAC Does not make a 5/8-24 Piston.

Subsonic 300 blk is perfectly fine out if the tirant. You can just as easily buy or make a 5/8-24 to 1/2-28 (or whatever piston you have in your tirant) works just as well. That's what I use for 300 blk with my osprey.
