No, it's not possible. You would instead use the Namespace.AddStore method to open the .pst file. Note, though, that Microsoft supports only ..pst files on local drives, not network access.

We archive old email in PST files to get them off exchange. if a user has
several mailbox's open it's no problem to get access to their folders via
GetSharedDefaultFolder, however if a user has an outlook data file open (PST)
i can't see a way to get access to it via GetSharedDefaultFolder, i can't
resolve the name. should this be possible?
Thanks,
Steve
