Yes, this is possible.  You should access it from only one operating
system at a time.

I also strongly recommend that if you're going to do this across
operating systems, you use UDF[0] and not NTFS, FAT, or exFAT for this
purpose.  Linux can format drives this way for use across OSes.

These settings, user.name and user.email, _can_ be stored in
.git/config, but _usually_ are stored in the user's home directory,
which will differ between operating systems.  You can use the "git
config" tool to set them appropriately if you'd like.  I personally sync
my dotfiles across machines, which includes .gitconfig, which is an
approach many others use as well.

Git doesn't create branches unless requested.  It's possible that some
other tool on your system did.  For example, if you're using a file
syncing service (e.g., Dropbox or OneDrive) to sync data, that's
definitely not recommended and can cause problems like this.  If you're
using WSL instead of a true Linux system, that data could also have been
created by Windows.

It's also possible that this branch already existed on the server and it
may have shown up as a remote tracking branch with "git branch -a", in
which case attempting to check it out may have created a local copy.

Without more details or output from a program, it's hard to say what's
going on here.

If you want to delete a branch on the remote server, you can do this:

  git push -d origin linuxcompatibility

If you want to delete a branch locally, you can do this:

  git branch -d linuxcompatibility
