Sure! Just open the new version into Photoshop, then immediately Cmd A Cmd C Cmd W (select all, copy, close).
Then go to your existing TIFF file, and select the Background layer, then Cmd V to paste.
Immediately change the pasted layer to "Difference" blend mode. That's the easiest mode for this, you'll be able to move the layer around, and when it lines up to the underlying layer, it will be black. Make sure you do this at 100% zoom.
Once it's aligned, make it "Normal" blend mode again.
Finally, go to Image>Reveal All.
