Mootivation: I'd love to migrate all my data on my mac to kubuntu.
What happens if I copy my mac user /Users/{username}/ to a linux user (the equivalent of /Users/{username})?
Will anything break?

Don't.
Just copy your user data over: documents, pictures, etc. Do not copy configuration data over from a totally different operating system. Many of that configuration data will not be used so just take disk space, and, worse, there is a chance that you will cause some annoyances or problems because of incompatible configuration information.
