If that echo or reverb is destructively mixed into the song's tracks and not being applied in realtime by a plugin from within a recording software, then the answer is an unqualified, "No".

Others have asked about that before here.

The lesson that should be learned from all of this is that you should always create and archive two mixes when you add reverb, echo or any other time domain effect to your project -- one completely dry and the other with the effect(s) on it. That at least will allow for a revisit of the Dry Tracks in a future Mastering session.
