Your posted circuit does not contain any DC bias on the input so I assume it's Class C. Overdriving the input will distort the signal but if it's constant carrier (e.g FM) you just produce more harmonics. If correctly filtered and you don't cook the transistor in the process, it should work fine.
If you need a linear circuit for SSB or AM then your circuit is a no brainer.
You can clamp the input using PIN diodes back to back to prevent overload.
