Wikipedia is dual-licensed under the GFDL and CC BY-SA 3.0 (http://en.wikipedia.org/wiki/Wikipedia:Copyrights); stack exchange content is also under the CC BY-SA 3.0, so provided attribution is given (eg, a link to the specific revision in wikipedia so the edit history can be checked) it shouldn't be a problem.
