The book was not published in English, and I am using a different perspective in the paper, but the same qualitative data.

I didn't find any formal policies addressing this specific case, but my intuition is that it would probably be all right. It could be analogous to publishing sections of a thesis, which is generally accepted.
If you have a journal in mind for the paper, you could contact the editors and ask their position on the issue. If and when you eventually submit the paper, you should include a note to the editor explaining the situation, and probably mention this in the text of the paper as well. If you disclose everything, there won't be any ethical issue; the editor can make the decision, and I expect there would be some good journals that won't have a problem with it.
Factors that might be relevant:
Was the book offered for sale publicly, or distributed privately among colleagues?
How many copies were produced/sold?
Did you retain the copyright on the book?
