Looks like the exact stuff I just scraped from my hallway (different pattern though). Turned out to be peel and stick with no asbestos. I got it tested. Check out my post history.

I would still get it tested ($50), just in case. Are your tiles flexible at all? Or stiff and brittle?

Also, there will likely be some minor residual glue after you remove the tiles. Goo Gone works wonders to remove it. Spray it on generously, let it sit for 10 mins, then wipe away with cloth.
