They can be opened with a pentalobe screwdriver. The 2018 MBPs also have a T2 security chip now, which intermediates all access to the drive. It has internal unremovable encryption keys which are paired with the drive, so even if you could move the drive to another machine, the data on it would be useless anyway. Your data should never be held on the internal drive for more than a few seconds really. With a decent MDM solution, restoring the standard settings and applications should take no more than a few minutes. As such, in modern times, there should be no real use-case for moving the drive - just set up a new machine instead, more like the Chromebook way of thinking.
