I concur. If another laptop of the same model doesn't show the problem, that points to a manufacturing defect.
It can be easy to route noise through an area the designer didn't intend with a simple solder blob or a defective power supply bypass capacitor. 24MHz could just be a frequency of a crystal oscillator.
I'd want to know the actual power level of the transmission, but to measure that accurately, you'd want to put the laptop in a shielded chamber.
