Just a question for clarification, since I will be going the same way
some time next year:

Are we just talking about domain function levels (Windows Server 2016
should run as a DC on the 2008R2 level just fine), or is it really not
possible to join a Server 2016 to a domain with a samba DC?

The way you describe doesn't really make sense to me - either you would
first set up a Windows Server 2008R2 as DC, transfer the FSMO roles and
demote the samba DC, but then you can't "upgrade the windows DC to the
domain function level you require" since Server 2008R2 obviously won't
support any newer function level. You would have to install yet another
Server 2016 DC or upgrade the DC to Server 2016 first. Or do you mean
"set up a Server 2016 as a DC using the 2008R2 level, transfer the FSMO
roles, demote the samba DC and then upgrade the function level"?

Thanks,
