No. The key question is whether the SSP end supports GRUU (as originally posted), so it is available to a PBX UA if it requires a service that uses it. While I agree that GRUU is currently optional for registrars to deploy, I suspect that if we started SIP now, an appropriate mechanism would have been a mandatory element for registrars. Optional is possible in the direct UA to registrar case because the UA at least has some direct choice over which registrars it uses. In the PBX environment, a UA wishing to use GRUUs to implement a service has very little choice over which business trunking arrangements it uses. So no support of GRUUs at the SSP in business trunking means no service using GRUUs within the private network.
