Not really. If the Kerensky government had negotiated peace with Germany, it could have survived. The Russians were sick of WW1, that is why it happened. Let's not forget it was the Czar who started and bungled the war in the first place. Without the Czar, we would have been spared both WWI and WWII and communism!
Like it was at all possible for a government that was heavily in debt to the Entente to peacefully break out of the war and not become a hated pariah. It's more likely that the British and French would've subsidized Kornilov couping the state to turn it into a military dictatorship to keep it in the war than that they'd have allowed it to peacefully leave the war.
