The "smoke" itself is unlikely to damage any components. The only risk is direct contact with plastics. And that would require somewhat lengthy contact. The possible effect would be causing the plastic to become brittle and fracturing. Overall, I don't see much risk. The problem with using dry ice "smoke" for leak detection is that once it warms up, it quickly becomes invisible. And since you're looking for vacuum leaks, you would have to pressurize the system in order to look for leaks. Vacuum leaks can be extremely frustrating to locate. I've always replaced all the vacuum lines if I suspected a vacuum leak. But if you have already done that, and still have a leak, things get more difficult. With these old cars, the plastic components, gaskets, etc., can become a source of leaks, and the "replace until fixed" method can be expensive or impossible. You just have to be smart when troubleshooting. What are the symptoms that lead you to believe there is a vacuum leak?
