It is possible to send anything.

No, the client MUST reject the NOTIFY with a 481 response. See RFC 6665, section 4.1.3: 4.1.3. Receiving and Processing State Information Upon receiving a NOTIFY request, the subscriber should check that it matches at least one of its outstanding subscriptions; if not, it MUST return a 481 (Subscription does not exist) response unless another 400- or 500-class response is more appropriate.
