Perhaps another way to look at this is, "overload" of a tuner is usually a term used to describe a condition where non-linear operation occurs in circuit that is intended to operate in a linear fashion. In that context, overload is not expected to cause damage to any component.
To expand on protection diode operation, simply driving a diode into conduction is not harmful. Harm would result if the current was excessive and sustained. The diode rating would indicate how much current and power it's capable of handling without damage. numbers range from a few Milli-amps on up. So I would expect you would need a signal anywhere from 10 to 30 dB higher than the conduction threshold to begin expecting damage.
@everyone - Let's not be in a hurry to stifle honest questions, particularly those clearly motivated by a sincere desire to learn.
