I would be presumptuous to attempt to speak for all of veganism regarding any question.

As me, veganism is about living a life, or in other words, behaving in a way that best aligns with my intentions to live as healthfully, joyfully, and as kindly as possible. Importantly, it is never far from my thoughts that each person that I meet is likely doing some form of the same. What behaviors manifest from that intention is what gives rise to the wonderful myriad of experiences that I enjoy each day. Placing effort into determining what is right and what is wrong about the behaviors of others, or what others should or should not do is not part of living my intentions.

To the degree to which veganism is dogmatic and dictates what behaviors one may engage in it is of no interest to me. To the degree it arises from my intentions, rather than directing them, it is a wonderful element of my life. That being said, the question “can a vegan be…?” is of no value in my humble thoughts. A question that may have value in considering is: Does abortion (in the specific circumstance) sync well with my intentions?  Related to that question it is important to me to remember that I can only answer that for myself.

Veganism, as me, is not a set of rules defining who is deserving and who is not deserving of the moniker, but is instead a word that describes a way of living that results from internally created personal directives.  The word is useful in the sense it helps others have a general idea about my choices - for example it easier to order in a restaurant when I share that I am vegan than it is to explain what that means to me.  It is not the case that "I can only eat these things because I am vegan" but is rather, "I eat these things because the are healthy and are kind to my fellow beings and 'being vegan' represent that choice in a simple manner".

Thank you for the question and Peace to You always.
