You're thinking of the Tomb of the Giants. It could be possible that they're the same area, assuming the Catacombs and Tomb are much larger than what is initially shown.

That said, it might very well be a completely different catacomb, as the Demon Ruins in Dark Souls III are almost certainly a different part of the same location from Dark Souls.
