Yes but not completely straightforward. There is no generic ID on the answers as a whole so you can add that then link to that anchor.
First check up advanced themes if you haven't already: http://www.question2answer.org/advanced.php#theme-advanced then try this:
1. Find where the "qa-a-list" element is output and change it to <div class="qa-a-list" id="qa-answers">
2. Find the part which links the title to the question page and make a note of the code there.
3. Find which function outputs the answer count and add your link to the question, but put #qa-answers on the end. You'll also need to check the number of answers I guess to avoid linking "0 answers".
PS. Sorry if this is a bit vague as I don't have the Q2A code on the computer I'm using but I can add more details later if you need.
