In my experience, your CV is your CV, and it should list basically everything of scientific significance about you (unless you're so far along in your career that you can do an impressive "highlight" CV). The main decision available to you is how you order and cluster these things.
Thus, if your CV is already ordered and grouped to put your best foot forward, scientifically, I don't think you need to do anything else in particular to tailor it for a travel grant application. I certainly know that when I have been in the position of looking at student/early-career applications to decide on travel grants, the full package is generally small enough that it's easy to see the significant bits no matter how things are formatted.
