You could try. They are common mode devices so should suppress anything that the power wire carries inside as the common mode signal, that is acting as an antenna. The effect of it entering the chassis and the part of it capacitively coupling into some RF sensitive circuitry might be attenuated.
How effective it will be - I am not sure. In essence Y-caps do the same job. I did not see them being that effective for the radios.
For cleaning the power line of the CM RF they (and ferrites) are effective. That is when you protect MAINs from your device spewing interference in The Grid.
