I am wondering if UA or AC policy applies to baggage on this ticket as United allows through checking bags on separate tickets on alliance carriers while AC seems not to based on the responses in the thread.
To add to the response above, I suspect you'd have better luck asking the CA transfer counter at HKG. They may be able to re-tag your bag so you won't have to claim and re-check it landside. My experience with this predates Covid, so I'm not sure if things have changed.
