Yes, you can use a USB or Tbolt drive to transfer files from one Mac to another. That's a straightforward and easy way to move files. It isn't a way to backup a Mac, but for simply moving files from one machine to another that's fine.
Another option is to use iCloud Drive. Set it up on both machines, and as you create and use files on one Mac, those same file will be made available to the other, as long as you use the same Apple ID to log in to iCloud, or grant access to another Apple ID with sharing.
