I can't answer for all of Europe, but April Fool's Day is definitely celebrated in the UK and Ireland. I don't think that I've participated in any jokes directly since my school days, but there are usually some good stories on TV, in the newspapers, and increasingly on the Internet (if you can separate them from fake news!).
One of the most famous British TV hoaxes is 60 years old this year. In 1957, Panorama, a still-running, hard-hitting, investigative current affairs documentary show looked into the spaghetti harvest in southern Switzerland. Spaghetti wasn't widely eaten in Britain back then, so most people didn't know where it came from. Check out the spaghetti being picked from the spaghetti trees and laid out to dry in the sun:
We briefly covered the French version of the tradition when I was at school. They call it "Poisson d’Avril" (literally "April Fish"), which originally related to the practice of sticking a fish on the back of "fools" who did not accept the calendar change (having the New Year on January 1st instead of April 1st) imposed by Charles IX.
Of course, in Hazzard they celebrate Sadie Hogg Day on April 1st .
