Absolutely. If you are supposing that all the tyranids have been spliced into a single hive mind they could scythe through the Imperium to Terra itself. The 1000 or so Space Marine chapters and billions of imperial guardsmen would be swamped by pure numbers. Even titans have been recorded being pulled down by massed gaunts. The Imperiums only real hope would be in it's fleet.
