I don't see why not.  For people trying to access your systems, just the change 
in your corporate DNS servers will be sufficient.  For what the system thinks 
its name is, there's only a few places where this is stored.
/etc/hosts
/etc/aliases.db
/etc/resolv.conf
/etc/HOSTNAME

Now, changing it with YaST is the simplest method, but I can't say for sure 
that when you save the changes that YaST won't restart the network.  So, start 
with a test system that can tolerate such a possible interruption to see what 
happens.
YaST -> Network Devices -> Network Settings
or just simply "yast lan" then select the "Hostname/DNS" tab.
