Yes, as they did in Þe Olde English, too. The problem is with using "ye" in place of "the", because nobody ever actually spoke aloud a word pronounced /ji/ ("yee") to mean "the". Instead, they had a special character, thorn (Þ), which was pronounced like a modern "th", and in some scripts the loop on the right got raised and angled out and narrowed and eventually you ended up with something that looked like an ornate "y", which modern readers misinterpret as such and pronounce like "ye".
So when you see written "Ye Olde..." whatever, you should imagine it really says "Þe Olde...", and pronounce it "The Old...".
TL;DR: There were two different words, "Ye" and "Þe", one of which is no longer used and the other of which is now spelled "the".
