Yes. Suppose you're communicating with signal flags. You have a black flag and a white flag, and assign them to represent 0 and 1 respectively. If you can change flags once per second, you have a bit rate of 1 bit per second, and the baud rate is also 1 (1 flag change per second). Now suppose you have a red flag and a green flag as well, and assign black = 00, white = 01, red = 10, and green = 11. If it still takes you one second to change flags, the baud rate is still one. However, each symbol change now encodes two bits, so the bit rate has doubled, to two bits per second.
