No, this will not work as asked, for at least two reasons:

1. Just connecing an USB cable this way will not turn the other laptop motherboard into an USB to SATA converter. (You can share the HDD from that laptop, usually via Ethernet but possibly also via and USB to USB sort of connection, but you will need to configure some software for that. It will not work automagically).
2. Normal USB comes in master and slave mode. This is also why USB has two very distinct connectors. You can connect a master to a slave, but not two slaves or two masters. This is why there are no USB-A to USB-A cables

Some extra notes:

There is an USB to USB cable which actually is USB-A to "device which acts as a slave Ethernet - bridge- Second device which act as USB ethernet to USB master 'cable". Obviously this is not a mere cable, even though salesdroids may present it as such.

Second extra notes. Some USB ports can work as both master and as slaves. There are commonly only found on mobile phones with a micro-USB AB connector. They are not the default on a random USB port of a motherboard.
