Considering this, can you lay tile over carpet?

First, you should try to even out your existing carpet as much as possible. It helps if your existing carpet is low-pile as plywood is not that heavy. After putting the layer of plywood over your existing carpet, you can proceed to glue the pieces of carpet tiles according to your design or chosen pattern.
If you have a low profile carpet such as berber you can lay the laminate flooring right on top. If you have a higher profile carpet that is plush and padded (like we do) you need to lay a solid surface down to make it firm. We learned this the hard way.
