It happens all of the time. Hugh Hefner has taken it even further than that. He was dating his great-great granddaughters...0

the age difference is not even a factor. 10 years difference in a relationship is barealy anything. it definitely could work.
however i see the main difficulties being stage of life. someone who is 30 is probably in an established career, whereas the 20 year old is in university/about to finish university. priorities are likely to be different i. e. settling down, having kids etc. vs learning about their interests, exploring the world etc.
of course everything i have said is purely speculation and it depends on the people involved :)0
