The problem here is that the AD data is replicated between DCs and if a
DC is turned off, the logs will start filling up with 'cannot find
DC?' type messages.
The laptops are the least of your worries, the passwords will remain
valid until they connect to a DC again.

I think you need to reconsider this, perhaps just use one DC on bare
metal, you will not get replication errors if there isn't another DC to
replicate to and you will be able to turn this off when required. You
will have to backup this DC regularly, just in case of a computer
failure, but these would have to be stored off the DC, perhaps on a
portable HD.
