That's always a possibility.
Some tuners also can act as low-pass filters or even as a parallel tuned
circuit, i.e. a bandpass filter. If the dominating noise contribution
is from a frequency-limited source such as a man-made source both could
work to lower the noise in the receiver. But I don't think this happens
