Most likely it will. It is not exactly "if LPC will handle it", but more like whether the two parties will understand each other. In a perfect world, you just need to multiply a bit's time times the number of bits in your word (7, 8?) plus the start and the stop bits and see if the stop bit ends reasonably in range (bits are compared at their mid-point). Since the world is not so perfect, you must take into account the rise and fall ramps of your transmission line as well. If both devices are 3.3V or 5V and in the same board, you can reasonably ignore the rise and fall ramps, since they are so sharp.
