Nopes, it requires IPv6, and Teredo is just a helper.
I just did a 'netsh interface ipv6 delete interface "Teredo"'
or do it by number et voila... it works ;)
(Would be a really odd and stupid requirement if it didn't)

Delete this one and you are off.

Address selection algo's simply pick the 'closest' interface.

Note that one can also explictely disable teredo using:
'netsh interface ipv6 set teredo disable'

And netsh does a lot more, imho 'netsh makes your windows look like a
cisco' ;)
Note that Teredo IP <-> Teredo IP could be faster than routing it over
the
IPv6 backbones.
