Probably not. Shimano is very conservative on their front derailer ranges. I’m running 24 tooth difference now on my touring bike and have run up to 28 tooth differences on the same derailer. They work just fine. Try the new gearing first with the current derailer before you buy a different one. If it doesn’t work then get a new derailer but don’t run out and buy one before you try the new gears.
