i2c bus arduino leonardo with lcd whithout ports 2 &3

Hi, is posible to use ports Sda & scl for display with i2c bus?

I'm not posible use standard port 2 & 3, this ports if in used.

Thanks

How are the pins 2 and 3 used ? Are they used by another I2C device ? If so, it is absolutelly possible to connect more devices to one pair of I2C pins ...
