I'd recommend against it, because even though the network is not
connected to the Internet now you never know what the future holds.
Even if it's never connected there are always things that seem to pop
up and cause problems.

Also, if you're address allocation policy has been so badly managed
that you've run out of space in 10.0.0.0/8 adding more IPs to the pool
isn't going to help for very long.
