    Possible, if:
    - You have a list of MAC addresses of known machines and/or know which machine is which on arp level.
    - And you have a valid account on that "other computer".
    Another possibility might be to shutdown the port this "other computer" has on your switch.

    Basically you would list the arp cache and see what IP the other computer has.
    Another way of finding the IP is to watch for network traffic and try to match it to known PCs.

    May I ask, what the motivation is?

    It depends on your actual network setup, what and how to do.

    Do you have control over the gateway and/or switch and/or router?
    For now I will assume, that the two laptops are connected over wifi to a soho accesspoint/router.
    If so, then I would suggest to login to that routerīs admin webinterface and look out for the network overview
    or connected wlan devices.

    If there are only two active leases on dhcp (yours and the other) then it shouldnt be too hard to guess the other one
    Once you have the IP, try to connect.
    The method o connecting depends on the capabilities and configuration of the other machine.
    Is it a windows/mac/linux?
    Is the appropiate daemon/service (ssh/vnc/remoteaccess/etc)
    Are remote logins allowed?
    Is there maybe a firewall blocking your access?

    Make sure, the ssh server is installed and started on the other laptop.
    The package is called openssh-server.
    This should install it:
    Code:
    apt-get install openssh-server
    Then ssh into it with
    ssh X@IP_Address
    With X being the remote user and the IP address of that laptop.

    Without any remote login method (ssh/vnc/etc): no.

    You can maybe grant/revoke the network access this machine has on the router.
