Running under carpet - especially in a traveled area - is not advisable. There's usually a work-around, though. In my case, I have a basement so I knock a hole in the sheetrock, then drill up inside the wall and drop the cable into the basement to run it where it has to go. You can do likewise with an attic.
Also, there is a goodly space behind most baseboards, so if you don't go overkill on the cable thickness (use thinner jacket), you can often run the cable behind the baseboards for quite a ways.
Every house is different, so you may have to be inventive.
