How about from Windows 10 to Linux? Can I buy a Linux disk and just put it in the CD drive and have it deport Windows back where it came from?

In most cases, yes, provided you can ensure you have first taken care of any Secure Boot problems that can arise or brick something like the Samsung, ASUS, or other computer motherboards that have a UEFI Secure Boot or other problems. Search the Internet for articles about: Microsoft UEFI Secure Boot .
You don't need to "buy" a Linux disk, though it might be simpler for you to pay a few dollars than to create an installation DVD or USB drive from a downloaded ISO file. For Linux Mint, the free operating system downloads are here: https://www.linuxmint.com/download.php
As for deporting Windows, when you install Linux you can choose whether or not to keep your Windows installation in a dual boot setup.
If you choose to overwrite your Windows installation instead of using dual boot, make sure you have all your personal data backed up to another drive.
