It should be possible, given a few assumptions.

When you say "which cell tower it's currently connected to",
will these devices be actually connected (with a
circuit-switched connection), attached with an active GPRS
session, or in idle mode (camped on a cell but not interacting
with it)?

Reading the cell ID should be straightforward in idle mode, but
will be trickier if the laptop is talking to something else
/through/ the card at the time. You may have to momentarily
suspend that connection/session, in order to have a brief
conversation with the card itself.

Some networks in some parts of the world broadcast a textual
cell name (a "cell broadcast" or "area info" message) as well
as a unique numeric cell ID. With most modern GSM modem cards,
reading both should be possible.

But good luck if you're looking for software "off-the-shelf" to
do these things.
