If the exiting floor is lino/sheet vinyl directly on a wood subsurface and the flooring lino/vinyl is in sound (as in not lifting, tearing, bubbling) condition. Glue and screw a backerboard such as hardy backer over the lino/vinyl. Use a construction adhesive and lay the backer down on the existing flooring. Stagger the seams. Screw every six inches. Now you have a solid stable surfcae to apply ceramic tile. Install with a modified thinset.
If you have a laminate floor as in your original post. Remove the floor inspect the new surface. If sound then follow the above instructions.
