Yes.

The NEC was written by very good engineers, and has included input from
some with excellent background in audio, video, and RF. I haven't found
anything in NEC that is in conflict with good engineering practice with
respect to EMC in any of these systems.
In some systems, it may be necessary to study and use the methods
permitted by various exceptions to the simpler paragraphs (for example,
isolated ground wiring). In isolated ground systems, everything is still
bonded together, but in a well controlled manner that is most suitable
for the system in question.
