No, the list is far from complete. Also, there is quite a number of cases, where a word with different meanings almost always uses the diminutive in one meaning, almost never in another. Would that count as a difference in meaning or not?
In fact, there is a general category of words where a shift exists in meaning: An 'uncountable' word (one that cannot get 'een', but only 'de' or 'het') can become 'countable' in the diminutive. The words "gein" and "plezier" in the list are of this type, but similarly there are cases like "aardigheid" (the property of being nice) versus "aardigheidje" (a nice thing to do).
