Parliament can indeed do that, but it would require either the consent of the House of Lords or the application of the Parliament Acts (which is a multi-year process). My suspicion is that the Lords (where the government has no in-built majority) would vote down the new Act on the basis that it was an abuse of process. The backup option is a German-style 'technical' declaration of no-confidence, where the Prime Minister whips their MPs to vote no-confidence in the government for the express purpose of triggering the Fixed Term Parliament Act's clause. This would be effective, but would have a (relatively small) political cost in public perception.
