"It depends." We opened a 7 year old cheese for Thanksgiving that was perfect as it is a cheese deliberately packaged to age and allow tyrosine development (which people seem to like for its bite). I've had a 30+ year version of the same cheese which was very edible and enjoyable, though you had to like a cheese with some bite. Pairs nicely with a white wine. Would 400 year old or older cheese be good? Main thing I'd worry about is brucellosis or other contaminants.
