English Language Requirement using degree

I am currently studying for my Master's degree at a university in England. Instead of 3 years for Bachelor's and 1 year for Master's, I am doing a combined 4 year course which will give me a Master's at the end. However I have already completed the first 3 years, so although I have not graduated or gotten any certificates yet, if I were to drop out now I would be given a Bachelor's so I feel like my studies are already equivalent to a Bachelor's.

Is there any way I can use this as proof of my English language knowledge even though I have not technically completed a degree?

Thanks for the help.

No.
