All that matters is if you trust your VPN. You can torrent on Windows with a good VPN, and you won’t get caught. You don’t need linux to torrent safely.
If you’re worried about copyright notices, VPNs can help with that. If you’re worried about viruses, most viruses aim for Windows systems, but you can avoid them by keeping an eye out. There’s viruses for macOS and Linux, but due to the smaller scale of users, most people don’t bother hosting them online.
If you’re afraid your law enforcement is going to bust down your door, that isn’t going to happen even if you torrent hundreds of movies and shows a month. They mainly crack down on the people who host the content, your ISP would probably end your service before you went to court.
That said, if you want a more “secure” operating system, Linux can help beyond tormenting. Fedora, Linux Mint, Debian, are all solid choices for your first time use. Just know there’s going to be a learning curve, and if it gives you an error, read it carefully and search online, as others have had the issue before and are willing to help.
