So an apparently male athlete, who has been living their life up until about twenty years old as a male, who discovers later in life that they are really female, can transition to their 'real' sex, change their 'label' on their birth certificate, and if they qualify, with the appropriate tests, compete in female sports.
I believe so
but there is no reason to suppose that is relevant to Laurel's case.
It is interesting to reflect that in the example you postulate, the incorrectly categorised athlete would never have won any medals or championships in their original incorrect "man" classification, and would only have been a rather poor amateur.
For example, the woman world record 100m champion does not reach the standard of a good man club athlete.
The same is true of woman weightlifters, shot putters, rowers, tennis players, footballers etc.
