Not really, it may be better if you are on a wireless network but you are strictly limited by the type of line you are on (i.e. copper wire) and the distance to your nearest broadband exchange. The 10mb internet will increase your download speed up to 10x (based on your distance from the exchange) but latency will remain the same.
The only option would be to sign up for FTTC (fibre to the cabinet) if it is available in your area, as this would improve your latency (ping) so you would get probably < 50 in game. I have FTTC and I can get 10-20ms ping in game if the server is EU.
Hope this helps.
