The maximum bit rate that can be transmitted over a channel with bandwidth B is determined by Shannon C=B log(1+S/N)
Are there any techniques that could break this limit?

No, but the capacity formula you mentioned assumes a very specific channel. Other channels may have larger capacities (see "faster than Nyquist signaling", for example in this question).
Also, nitpicking but this is important: the bit rate over a given channel is unbounded; you can transmit as fast as you want. The capacity is the limit at which you can transmit with vanishing probability of error.
