Sort of.

The request path was:
  Client or peer cache
    -> Squid as a proxy
       -> Squid as a accelerator
          -> origin server.

The difference is that older versions of Squid had a less strict loop
detection that only gave a warning on request paths like this. This
has changed in recent Squid versions to deny the request since a lot
of people had the problem that Squid infinitely asked itself on some
kinds of requests when acceleration is enabled.

You can, but you need to take special care if you are using the
accelerator as a proxy to stop the proxy from using itself when
requesting objects from the accelerated host.

See above.

Perhaps, if a reasonable way to do it could be found.
