Maybe. I have an earlier model with centerpull braze-on posts. The long reach MAFAC RAIDs I used swing out wide enough for 40+ tires. The issue with the cantilever posts on your Pro Tour 15 is the posts on the fork are brazed on fairly close together. This was done on most every cantilever compatible fork built during this time period. The pre-mitered posts must assume some fairly wide fork crown, most of the ones I've seen allow for maybe 35mm wide tires to get past the brakes inflated.
Looking at your photo, just measure clearance with the brakes opened as shown below.
