Yes of course.
Unlike US unis European unis do not have a same application process. UK has something similar to common app called UCAS.
Do a quick Google search for other countries. Not many unis in Europe are taught in English. But there are some that do. One of them is Jacob in Germany. It uses common app.
Do a quick Google search and if you have any specific questions then post it here someone from that country or uni will get back to you.
Best of luck.
