Good day.
I suppose the title says most of it.
I have a very well adhered vinyl product that DOES contain AESBESTOS, and I am validating the options of not removing it.
It is well down and on a solid slab of concrete of undoubted integrity.
I have heard anything from etching products & then skim coating first to soak (keep it wet during removal) it and pull it up.
Thoughts appreciated on laying tile overtop and not removing…or convince me otherwise. 🙂
Thank you,

Backerboard
The only possible way to cover this without removing it would be to use backerboard. But even then you have the issue of laying the backer board to the old vinyl. Adhering this would be as problematic as the tile. Mechanical fasteners would be a pain in the butt.
Bite the bullet and remove the old vinyl.
I'm reasonably sure that it's often recommended to just tile over it. It functions the same as an anti-crack membrane.
I'd be laying tile over it tomorrow. Lots of tile guys see well bonded vinyl as a plus since it acts like a crack membrane
First was my kitchen, ceramic tile over the vinyl, 8 years ago. Used a special primer, pink and unbelievably sticky. Ate the plastic guards off my kneepads. Then last year I did our large bath, no primer, just thinset and ceramic on the vinyl. Both are working fine. Well-adhered vinyl looks to me like the isolation the commercial products offer. I've got cracked concrete under both, but that's another story.
Without the primer, I sanded the bath vinyl but if there hadn't been any shine I would not have bothered. Just make sure it is clean. Modified thinset isn't very picky. I wouldn't touch that asbestos, isolate it.
