No, but all of the different Einherjar chambers are in the same "Zone". Shout doesn't reach across them because the distance is too great, but a region-wide channel would appear in all 10 chambers.

Edit: And people can shout in Dynamis now =/ it's not like everyone in the zone is in the same linkshell these days.
