MapInfo Pro - does an object shift location when changing from a Lat/Long (non datum) projection to a Lat/Long (datum)?

Products affected: MapInfo Pro™
There should not be any shift between Lat\Long systems because if one Lat\Long system has no datum definition there is nothing to convert from so MapInfo Pro does not do a datum conversion. There can be a very slight shift if the destination coordsys is bounded since MapInfo Pro may be increasing the internal precision of points.
