Yes, and the UUID is preserved if just delete a partition:

Before:

/dev/sda1 --> LFS-system ( / partition)
/dev/sda2 --> unformatted partition; will be deleted
/dev/sda3 --> boot partition ( /boot)

After:

/dev/sda1 --> LFS-system ( / partition)
/dev/sda2 --> boot partition ( /boot)

The boot partition will have the same UUID as before, because
file system wasn't modified.
