Ceramic Tiling over vinyl tiles

In the front porch, I have peel and stick vinyl or linoleum tiles. I want to replace them with ceramic or porcelain.

Need to know if I can just tile over the vinyl or need to take them out and then throw the OSB as a base for Ceramic tiles. I would prefer to tile directly over the vinyl to save time as taking out 50 odd peel and stick tiles by heat gun would be a good half a day project.

Thanks all!!
