You probably can, but you may need to retard the spark some (I'd guess maybe 1.0 degrees) because you're probably burning a mix that's actually 90 octane. However, it probably won't matter much. If the knock sensors detect "ping", the spark will be automatically retarded - a lot, and that will prevent damage. But retarding the spark could actually give you better performance right now.
