Perhaps in times past when their numbers were much greater, however the Space marines are far too few to defeat even one of the hive fleets now, do not get me wrong the Space marines are still essential when fighting these invaders but regardless of what lore you're following it only takes a few nids to bring down most space marines and te Tyranids outnumber them by billions to one (Correct those numbers if i'm wrong). Personally I believe that the one thing that currently exsists in the Galaxy that could save the imperium is quite ironically, the Warp and the Chaos Demons although some amount of cooperation must be used... If the Chaos Gods decided to leave the Imperium alone for a while (Once the rest Tyranid Hive fleets enter the Galaxy they would be fools not to) then they could use their daemons to fight of the Tyranids, this would have many advantages.

1: The Tyranids would have little to no biomass to consume while fighting Daemons, and so this loses their main advantage, the ability to grow...

2: If the Imperium does decide to "work," with the Chaos Gods then a steady yed large supply of Sacrifices could keep the Daemons and Warp Stroms arriving constantly (However given the Imperiums reputation this is highly unlikely)

3: The Chaos Gods and constant attack from Daeomons may "weaken" or possibly destroy the Shadow of the Warp, giving the Gods a chance to enter the Hive mind's collective conscience (Altghough I believe this oppurtunity will only last a few seconds) They will not be able to corrupt on control him (Or them if each hive fleet has it's own, I don't really know) but they will most certainly be able to cause havoc or slow it down, giving the Daemons and perhaps the other races of the Galaxy to butcher the Tyranids and drive them back (However So long as the shadow of the Warp exsists I believe that one can never obliterate all the Tyranids)
