Yes, as the others have said, you can earn money from HubPages in the UK. Just follow through with those tax questions that you saw. It's not as daunting as it first appears. You need to do this because HubPages is a US company and so any earnings are taxable by the US government. However, the US and UK have a reciprocal tax agreement which means your earnings won't be taxed by the US government. You'll still be liable to pay tax in the UK for any earnings, though, as you would with any 'self employed' earnings. This agreement means you don't pay tax to both the UK and US governments. But first you need to complete that tax information section of HubPages.
