Tile over old mortar bed?

Tile over old mortar bed?
I am re-tiling a fireplace surround. I have removed the old tile and what is left is a 1/2" to 1" thick mortar bed. It appears to be intact and secured to the wall.
Should I remove the old mortar bed before placing the new tile or can I just apply the new tile with thinset over the existing mortar bed?
