There are a number of flaws in your argument:
1) A royal charter is a formal document granted by the monarch giving an individual or a corportate entity a right or a power. That power may be to award degrees, it may equally be used to establish a city, company or to grant a body a power to award other qualifications.

Just because an organisation has been granted a power/established by a royal charter, doesn't mean they can all award degrees. For example - the constitutional basis of the BBC is the royal charter - does the BBC therefore claim it can award degrees?

2) A recognised body is an institution granted degree awarding powers by royal charter, all such organisations are listed here:
http://www.bis.gov.uk/policies/higher-e ... sed-bodies
You will note that ACCA does not appear on this list, instead it appears on the list of listed bodies, which are institutions or bodies, which, deliver courses that lead to degrees awarded by Recognised Bodies.
http://www.bis.gov.uk/policies/higher-e ... ted-bodies
Hence, ACCA deliver a course that can lead to a degree awarded by Oxford Brookes. It cannot itself award degrees.
3) The requirement is that you have been awarded a
degree at bachelors, masters or PhD level. The requirement is not that you have been awarded a qualification equivalent to a degree.
I cannot see that you can therefore argue that completing the fundamental ACCA papers alone, means that you score the points for qualification as
a) The requirement is that you have been awarded a bachelors, masters or PhD degree, PGCE, PGDE or Scottish HND
b) The qualification is none of the above
c) ACCA does not have degree awarding powers
