If you don't plan to expand the swap partition, I would recommend just deleting the swap partition -- you could either make it a new ext4 and use LVM to combine it with the shared storage, or if you're going to combine your EFI partitions you could grow your Mint partition to include both the SUSE EFI and the swap partition -- and using a swap file instead, as another commenter mentioned. You honestly really don't need swap space regardless with 16gb of RAM if you're really just using this to run a web browser, but you can easily set up a swap file if you want one.
