Tiling underfloo-heated, vinyl covered bathroom floor

[trem]

The current floor is 'wetroom' vinyl covered (with margins running up the walls for c. 4ins), under which there is underfloor heating. The floor base is concrete. Can I tile directly onto the current floor (having first thoroughly cleaned and 'roughed' the vinyl)?
