I can report that the computer renaming worked.
As it turned out, only the cn was incorrect ...
ldbsearch -H ldap://DC1 -UAdministrator 'CN=DT06'
dn: CN=DT06,OU=Desktops,OU=Computers,DC=domain,DC=com
objectClass: computer
cn: DT06
operatingSystem: Windows 10 Pro
displayName: WH23$
sAMAccountName: WH23$
... so a simple LDAP rename worked ...
ldbrename -H ldap://DC1 -UAdministrator
'CN=DT06,OU=Desktops,OU=Computers,DC=domain,DC=com'
'CN=WH23,OU=Desktops,OU=Computers,DC=domain,DC=com'
... and then for future full rename on the domain, we will use ...
net dom renamecomputer -S OLDNAME -U OLDNAME\\administrator%secret
newname=NEWNAME account=DOMAIN\\administrator password=topsecret reboot
Thanks.
