I meant general audiences would not understand a one-word reference to 'Windsor' (single word) as meaning 'The person FKA Prince Andrew'. Whereas 'AMW'/'Andrew Mountbatten Windsor' might. 'Windsor' until now referred to the entire UK Royal Family, various towns, the castle in Berkshire, the tie knot, etc.
I believe general audiences would understand a reference to Windsor to mean the person called Andrew Mountbatten Windsor in the previous sentence. The royal family are called the royal family most commonly. Various towns, the castle, and the tie knot were not in context.
