The DRO may be slow, but practically all linear scales are constructed the same as the rotary encoder and operate exactly the same way, one thing you have to watch for if you use one in place of a rotary encoder is that some are sine-wave out and need conditioning (squaring up), Heidenhain use both types alot.
