If they are always on the network, it's trivial, you just boot from the network as with any other machine.
If they are often on the network, you can use occasional rsync, for example to the system partition either at boot or in the background. That way, boot is possible even if disconnected.
If they're not often on the network, and you are seriously considering doing this at all, I would reconsider which problem you are trying to solve.
Also: I don't know about anyone else here, but I would prefer not having a company manage my laptop. The use cases for such a scenario, in my view, are pretty hard to imagine.
