Yes, it is.
I use CVS history:

grep '^T.*|branchName|moduleName$'  $CVSROOT/CVSROOT/history | awk '-F|'
'{print $4}'

The trunk (HEAD or Default branch) seems to be indicated by "D".

I follow the recommendation in Karl Fogel's 'Open Source Development
With CVS' at

and create a branch from a regular (non-branch) tag at the branch point
first.  So I have to repeat the command above with branchName =
the-branch-point-tag to find the actual parent. With a little wrap and
glue, you can automate this by consulting 'cvs log' to determine if a
tag is a branch or regular tag.
