If it doesn't have one then it would entirely depend on if the motherboard originally had support for one and its simply not populated. If it never had support or never had an unpopulated place for one then I doubt its possible to do as you ask.
If you can get a spec sheet for the motherboard then perhaps you could hack one in but again its doubtful.
Perhaps it might be possible using the mic in line ? it shouldn't be too different from a dedicated line in port.
Thanks. In my case it's one of those Optiplex 3050 MFF and a really old HP laptop (so I doubt it), but I'd need to look up the exact audio hardware.
There is a headset port on the Dell, which I assume is a 4 ring minijack, and with the right splitter it should be possible to route line-in to the mic-in part of that, but mic inputs are (usually) mono, while the line audio is stereo. Also I read that the specs of such a port vary, and it might be necessary to electrically limit the input from a line-in as to not blow out a mic-in.
