Morphology
The expression combines 'lay on' (to apply or bestow) with 'charm' (to please or attract), so a learner who knows the constituents can plausibly infer it means to apply/display charm. However, the phrasal use 'lay on' and the pragmatic/colloquial nuance of flattering behaviour to achieve an aim are somewhat idiomatic and may not be fully predictable without exposure.
Etymology
The phrase lay on the charm may come from the image of someone who lays something on, like perfume or a coat, but here they put charm on a person with smiles and praise to win them over. So it now means 'to behave in a very charming or flattering way to get what you want'.
