Sure, CentOS is as good as it gets.  I was just using my oldest still-running 
system as an example - and it is well firewalled so I haven't been forced to 
upgrade it for security reasons. You just need to stick to distributions that 
emphasize stability and in most situations you'll want some scheduled downtime 
to do updates that might require reboots.  But even dedicated hardware will 
sometimes have required updates.
