You can have Sjogrens and schizophrenia, or ITP, SLE, Parkinsons..etc, but ME/CFS nope?
That's right because disabling fatigue is a recognised feature of Sjögren's syndrome so to add in a diagnosis of ME/CFS makes no real sense. And ME/CFS is defined as disabling symptoms without any other explanation because that makes a useful prognostic category.
This isn't really about causal relations either. If someone does not have consistent Ro and/or La then there is no recognisable cause to call "Sjögren's". There is just the syndrome , which is an effect, not a cause. And we know there are several routes to the syndrome.
