A portion of ancient oceanic crust that sits atop Albania and hosts one of the largest chromium mines on Earth also contains a huge hydrogen reservoir, offering a potential source of clean energy.

That is referring to “paleo” water, or water from a past ecosystem. You can sorta call it a fossil. But geologic hydrogen is closer to a mineral deposit, and wouldn’t be called a fossil in any sense. Not to mention there really is fossil hydrogen, which can happen from outgassing from fossil fuel deposits.
UNESCO sorta have a formal definition using the term ‘Fossil water’. I’m sorry that you don’t quite feel it captures the nuance you’d like but I’m afraid I’m going with their gatekeeping on the term rather than random internet guy’s.
You also can’t manipulate words either.
One important distinction is that geologic resources can be quite recent. A lot of underground hydrogen can be made right now via chemical reactions. It is closer to geothermal than what you are thinking.
