it is not advisable to install ceramic, porcelain, or stone tile over a vinyl flooring system. It should be removed.

you can remove the vinyl and underlayment if it has a underlayment by using a toekick saw to cut it off at the cabinets if you dont want to replace the cabinets. Usually tool rental stopes have them

here is more information on toekick saws:
