I doubt it because, as I said, Word did not even render the document the same on two different installations back in the day. Contrary to LaTeX, there is really no way to know what "opens on your computer exactly as expected" even means. We do not know what the original author intended it to look like, because we do not know how the document looked like to them. As long as there is no retroactive interpretation, like it happened with RGB, for example, the "doubt it" will stand.
