Cutting ceramic tiles laid on concrete
If the tile is well bonded, there's no reason to remove it. I would use construction adhesive under your wall plate, and I would use a masonry drill to put holes through the tile for your fasteners.

If someone wants to replace the tile down the road, they'll end up making the same cuts you would have. Why do it now if it may never need to be done at all?

If you do decide to make the cuts, a diamond wheel in an angle grinder will do well. Run a large vacuum directly behind the wheel to collect dust. It should leave very little chipping, and won't crack anything unless there's a loose tile or you get rough with it.
