433MHz receiver compatibilty
Short answer: Yes a superheterodyne receiver can "pick up" the transmitted signal.

Be aware that the transmitter side is a transmitter+modem: The transmitter accepts a digital input signal to be sent . And the super-regenerative receiver shown is a receiver+ modem: it outputs a digital signal.
A superheterodyne receiver very likely has no modem...it outputs an analog signal which would require an additional modem-type circuit to re-generate the digital signal.

The modules shown use a very simple modem scheme. It is often called on-off-keying (OOK). It is very similar to Morse code.
