I'm preparing a tiling project for hallway and kitchen. The floor is concrete with linoleum tiles glued on. Having tried to remove some tiles I have found that they are fixed very very well to the concrete floor. The linoleum itself is about 3-5mm thick and hard/brittle an therefore has no flexing.
Could I not just tile over the linoleum (assume to put down slate or vitrified porcelain), or ?

Lino breaths and will let moisture evaporate through it, covering it may make it act like Clingfilm and cause problems later on.
Also some linos react badly to adhesives.

I hope youre kidding. Your tiles will break like eggs. Floor tiles must be bedded all over onto something rock hard, not deplasticised lino!

Have you tried a pnumatic chisel?
It won't take much flexing for your tiles to make a nice snapping sound when someone walks on them :)
The tiles won't stick well to the lino and 2mm difference in thickness sounds like a rather uneven floor to start with. Best to remove the existing tiles and if needs be apply a self leveling grout to the floor.
I think you should be alright. I've floor-tiled my bathroom on top of cork tiles (that's the thinnish 3-5mm sealed cork - quite hard) with half-inch marble tiles and after two or three months, no problems. If there are any gaps (where you tried to remove the test one for instance) fill it smooth with a tetrion or similar filler. use a water/powder mix type adhesive and make sure you use a 5mm notch spreader. If you think about it, the only thing that could go wrong would be if the underlying tiles went spongy in patches, for example if the adhesive reacted with the lino. Highly unlikely.
