On some boards (like Leonardo, ProMicro -— see above) the SS pin isn't exposed (rather it is connected to RX_LED). So people wondered if it wasIt is not possible to remap SS to another pin to be able to use those boards as an SPI-slave. That's not possible slave as the AVR uses fixed SPI pins according to the datasheets (PB0-PB3 on 32U4). You could start to solder of course, but maybe it's easier to use a different board if SPI slave is needed.

The Leonardo and Micro do not expose the SPI pins on the digital pins, unlike the Uno and Mega. Your only option is to use the ICSP header pins, as illustrated above for the Uno. However the Leonardo and ProMicro don't expose the SS pin and thus cannot be used as an SPI slave.
