I would recommend dual booting if you can spare the drive space. If your computer has two drive bays (some of the gaming laptops do so I throw it out there), I always do two completely different drives and just have one set to boot by default. But it's a great way to try something out and see if you like it. One thing I would mention with deleting it later: Yes, you can delete the partitions and just resize them, but follow this link to also uninstall the GRUB bootloader if you decide to remove Linux Mint. That step can be done before you remove partitions or after, so don't sweat that.
Hopefully you enjoy it! I actually moved to Mint a little bit ago after years on Fedora, highly recommend it.
