Workshops with a BB at high school on CV for first-year summers?

When I was in my final year high-school, we had market risk directors and some HR people from a BB come to my school and give us workshops. It was in an eastern-european country, where they mainly have BO. I was wondering whether it would be okay if I could somehow spin it around, and not explicitly mention that those workshops were in-school instead of the office + call it an insight day. I'm in a western-european country right now, so I don't think that HRs between the regions will communicate just to check this.
