Your question holds no merit. IF this magical method to remove a fetus from the womb that is non-invasive, she has to consent to it, same as an abortion, if she does (and it acts as an 'abortion' in the way that she relieves herself of any and all responsibility to the fetus and subsequent), then no, she doesn't have a right to then try and break the test-tube and kill the fetus. That's how bodily autonomy works.
It's not cowardice to recognize your question as 'but what if' as irrelevant to the situation.
