Technically they could be trained to some similar level but that level is definitely less than optimal. The anatomical and physiological differences between men and women make the same level very difficult to achieve. For example, on average, your everyday active male will have a similar VO2 max to Olympic level women athletes
also, I do not think that women and men should compete against each other again for the anatomical and physiological differences
and on top of that, I also believe that and trans, especially mtf or vice versa should not be allowed to compete in any sport until after their hormone treatment is complete
