No, you can't train for an IQ test.

Yes you can. That's why the people who give IQ tests professionally will not allow a person to take it twice inside a certain time frame. They say the second test will have "artificially elkevated results", what they call "the practice effect". That's just another way of saying that the first test was training for the second.
Outside of that, there are also cognitive exercises people can do to increase certain sub-test scores. You really can increase your working memory with brute force practice and repeatedly practicing the sort of questions they ask will truly raise your score.
I've read stacks of books about IQ tests and the history of IQ testing. The history of IQ testing is riddled with what one might call "stupid assumptions" on the part of researchers about intelligence and how to measure it. The most famous of these assumptions is the one (that they have made repeatedly in different ways) that if a person is "intelligent" they will possess a certain body of knowledge that people "should" know. This has led to tests with racial bias and culture bias. I thought all this was ancient history until I saw test questions given to my daughter. They assumed a level of social knowledge and knowledge of other children and adults that any intelligent child "should" know. But of course an autistic child doesn't spend 24/7 studying the social world around them and therefore doesn't pick up that knowledge. They study other things instead- the design on many peoples' t-shirts, in her case. This is cultural bias but the testers don't even realize it because they assume that any child with intelligence will use it to learn all they can about interrelationships and school culture.
Annoying and also comical example of culture bias
A friend of mine had a son who was language delayed (but not autistic). She took him in for testing. They wanted to see if he had a receptive language impairment too so they showed him some pictures of food and when they said the name of the food, he was supposed to point to the picture. They showed him pictures of hot dogs (we are American), cake, ice cream sundaes, all sorts of things any kid who understood language would be able to point to correctly. He just stood there "dumbly", not understanding a word. A serious expressive language delay? No. A health food zealot mom who didn't ever give him those foods so he didn't recognize any of them. They scored him down anyway because the test was standardized. It's the little things like that which let me know cultural bias is still holding strong in cognitive testing.
