Not if the only way to open doors in this world is via scroll waving, similar to how Weiss waved her scroll over the CCT elevator and then it took her to where she wanted to go. They could disable Yang's scroll's unlocking capabilities. Yang might be able to steal one of RWB's scrolls, but they're probably keeping a close eye on them so she wouldn't get the chance. The only other option would be climbing out the window, but they'd probably have guards but outside the door and underneath the window in case she tried either of those methods.
