Yes, no, maybe. Whilst you would expect most airgapped systems to also be in buildings that intentionally block signals, there are a ton of "unexpected" interactions, some of which may give you ways to remotely transmit when no transmission is expected to be possible. Like the fact that USB 3.0 can interfere with the 2.4Ghz spectrum [0], thanks to resonance. Israel has also previously demonstrated malware called Odini [1] and aIR-Jumper [2] to bypass Faraday protections around systems and exfiltrate data.
