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

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.
