In theory, in the UK at the moment, the answer is yes.
You could, on your first ever solo flight, gain 3000 feet of height, fly for five hours and land over 50 km away. Providing an official observer signed to say you had done all this you would get your silver badge.
As mentioned above away from the BGA system you might struggle to find the necessary OO but, technically, they are appointed by the FAI and not the BGA.
