Backerboard
 
Is it ok to lay 1/4" cement backer board over existing linoleum flooring before laying ceramic tile or does the linoleum have to be removed ?

Removing the linoleum would be the best case because even if it's glued down it will have some air under it which will cause movement. Cement board holds no structure for tile, so air can cause backer board to move and cracking thinset and or grout.

Rmove the Linoleum! I have tried placing backer board over a linoleum floor in a small bath. It has been about 2 years and I just bought new flooring to do the job over. The sales person at the home store said it would work..... Wrong! Take the time and do it right the 1st time.

Jet & Bigguy are right, but don't go far enough. Chances are your vinyl is installed over 1/4" underlayment of some type. The 1/4" stuff needs to be at the curb too. Verify the layers you've got there and let us know in detail. If there is 1/4" wood, take it up with the flooring attached.

How old is the floor? If old, there might be asbestos involved. Let us know, take pics if you can.
