IQ in humans strongly correlates with almost any measure of performance you pick, so I think its definitely telling us some measure of capability even if not the whole story. I imagine people with ADHD do have trouble with some types of tasks (other than IQ tests), or we wouldn't think of it as a disorder? Of course, we can't necessarily expect this trend to continue for machines taking IQ tests! IQ tests may not test world understanding to a large degree, but definitely do test ability to adapt to new problems. Its hard to define understanding, so I prefer to stick with quantifiable measures of performance.
