Yes. The compartments have different targets and may respond differently to a fault or operating event. One suitable reading does not cancel the other warning.
What the observation tells you
The freezer may have received a fresh load, suffered a door gap or developed another problem while the refrigerator remains satisfactory. The exact design determines the relationship. Do not silence the freezer alarm simply because milk still feels cold.
A useful next step
Read the warning, record its timing and assess frozen contents using reliable information. Keep the fridge observation in the account without using it as proof that the whole appliance is healthy.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
