Normally it should be the case, I would have a look at the samba box for
error related to DNS (ie. impossible to bind on port 53). Which kind of
DNS setup do you have ? (internal, bind 9.x dlz, flat file) ?
Which DNS server ip the *nix box running Samba 4.0.x is using ?

Yes. From the Active Directory User and Computer you select the DC and
remove it, you might have to go to Active Directory Domain and Site and
remove the links to the old DC as well.
But if the s4 DC is working well the demote should work well.
