If you are by chance talking about radio control model servos, then
the answer is no (those are simple variable resistors).

If you mean large servomotors designed for machine tools or similar
applications then yes, there is a good chance they might work. On the
other hand, perhaps you could use the servos AND the encoders to CNC
your machine tool.
