Just to be clear, I am talking about running tinc on the host system and
using docker containers attached to the tinc interface on the host.

Yes, at the moment it is not possible to install/run tinc with a TAP
device inside a Windows container, see:
https://github.com/docker/for-win/issues/1909

I guess that is because a container with process isolation cannot
create/manage devices like the TAP device.

But it is possible to run tinc in a Linux container on a Linux host
using the network mode "host", see for example:
https://github.com/mback2k/docker-tinc

You just need to put the tinc configuration into a mounted volume under
/etc/tinc and make sure the container uses network mode "host".
