Nope, the name is the "binding" of the dhcp pool and not a property you can change.
That said - I wouldn't worry about messing things up - thats how we learn right? DHCP scope is a trivial thing that isn't bound to profiles like other parts of the config.
Note down all pool information. Delete the scope, click apply. Create Scope - click apply.
Edited - didn't notice this was Instant at first ;)
