Er... yes, but not easily.
Each NIC would need its own IP address; I'm not aware that you can
assign the same IP address to multiple NICs without a great deal of hassle.
It's relatively easy to share the modem across multiple NICs with
different IP addresses, but the final devices would not be able to talk
to other devices without setting up routing, which is reasonably
advanced. For example:
Modem -> PC -> Laptop1
...would prevent Laptop1 talking to Laptop2 unless you set up routing.
Given that you can buy a brand new network switch for less than five pounds:
...this is an extremely complicated way of achieving a very simple
result. Instead I recommend:
Modem -> PC -> FiveQuidSwitch -> Laptop1
If by "modem" you mean "Broadband modem with Cat5" rather than "USB
modem" or "pre-broadband modem", then you can achieve even better
Modem -> FiveQuidSwitch -> PC
