As this is a CentOS Linux, you could log on to the AirWave using the root account and change it by issuing the hostname command.

Well, the hostname is only a DNS name for the server. If you are not using DNS for anything today, this should be ok to change.
If you are using DNS in some way, you will need to make appropriate changes to other devices using the hostname.
Answering the question about using DNS today or not, will give you the answer if you will get disconnects or not.
