I know you're an experienced tech so I'm not trying to contradict you, but I believe the scale length is 25.5 inches either way (at least that is the specification), meaning the bridge is in the same position relative to the nut. String tension should be the same.
To elaborate, on a typical 24 fret guitar the fretboard is actually longer - the 24th fret is at about the same place the neck pickup would be on a 21 or 22-fret guitar (the 4th harmonic). The pickups are actually placed closer together, and the lower bout is a little deeper to accommodate the extra frets. Again though, unless the scale length is changed, the bridge will be in the same position relative to the nut - that's actually the definition of scale length - if the bridge were further back, it would be a different scale length.
