OP, if your island is set on top of the tile, this should be relatively easy, if the island was set and then the tile was installed you may be in for a very nasty surprise, especially if matching tile is not available. Proceed carefully so that you can reverse what ever you do. My first step would be to carefully remove the trim at the bottom of the island an see if the tile goes under the island. My next step would be to buy or borrow a borescope type camera and have a look at the actual flooring under the cabinet. This information will let you know how easy the island can be moved or relocated. Hope this helps and good luck with your project.
