Yes. It can describe any situation where a superficial layer of normality hides a deeper, often troubling, reality (e.g., 'The company's profits had a false bottom of accounting tricks').
A 'false bottom' is a specific *type* of secret compartment. All false bottoms are secret compartments, but not all secret compartments are false bottoms (e.g., a compartment in a wall or a book is not a 'bottom').
In British English: /ˌfɔːls ˈbɒtəm/. In American English: /ˌfɔːls ˈbɑːtəm/. The word 'false' rhymes with 'halls', and 'bottom' rhymes with 'got 'em' (UK) or 'lot 'em' (US).
