The short answer is YES you can.
BUT.......
Providing you run PREMIUM grade fuel.
Here is a short quote from a very long article. The article address is...

"Can classic cars run on today's petrols with higher octane ratings?
Yes. Using today's modern fuels with higher octane ratings won't harm the engines of classic cars designed to run on petrols with low octane ratings."

Hope this helps, there are other articles that say No you cannot but unless you have poor quality valve seats (which very few cars have) you are fine, just spend more $$ and upgrade to higher octane fuel to achieve the lubrication missing from leads absence.
There was a lot of hype when unleaded fuel was introduced (I remember them well, I was in the Auto industry at the time) about excess wear with unleaded fuel but studies and time have debunked most of those concerns.
There is somewhere a list compiled by the Canadian Government listing what vehicles have valve seat problems but I cannot locate it at this time.
