I don't really understand what you need to be explained.

Izanami is an immortal being that currently possesses an artificial body that was adjusted to her. That body is her vessel. That body, vessel, is Saya, a girl that is an artificial human, since her body is a man-made crystallization of seithr. Her body has the ability to infinitely amplify seithr, that's why she was chosen as the base for Prime Fields.

Boundary Interface Prime Field Devices are also made from seithr.

Kushinada's Lynchpin nullifies seithr, so, theoretically, if Saya's or Prime Field's body is pierced by the activated Lynchpin, these bodies could be destroyed.

We already know that if Izanami's vessel will be destroyed by the Lynchpin, Izanami will remain active.

As for Noel, currently we don't know how she became a god, but she can't be killed through normal means anymore. But the Lynchpin should be able to destroy her body, that's why Mu is protecting it.
