Mixing isolated grounds and equipment grounds

[55Chevrolet]

Is there anything in the NEC that prohibits using an existing isolated ground for an equipment ground?

No, but for whatever reason the Isolated Ground Conductor was installed for in the first place, it will not have this isolation after using it for a plane jane EGC.

Many times the isolated ground is pulled through one or more panels back to a main panel.

Do normal ground wires have to originate in the same panel as the branch circuit or feeder it's ran with? Maybe I am confusing ground wires with neutral wires?

I wonder if the isolated ground was originally installed at the insistance of an equipment manufacturer so that the equipment would work right and it didn't make any difference.
