I don't think it's advisable to use floor tile as a back splash for your stove area. But I do know, the peel and stick back splash material, made for being a back splash, is extremely strong stuff. I used some of that when remodeling my current house. You get one chance to stick it on, and it better be right the first time because it's not coming off to correct it, without ripping the wall with it.
Suggestion: Get the self-sticking stuff made for back splashes behind stoves and do not use the stuff made for floors. The back splash products are made to withstand heat, grease, splatters. Floor tiles will melt!
