I agree with Larry as long as you can comply with the required working space it's good to go. Is this panel in Canada?
 
this is a building code issue, not NEC. penetrations have restrictions dictated by IBC. if the stairway is fire exit, I don't see how you can install a panelboard in the stair well and comply.

(Amd) 1023.5 Penetrations. Penetrations into or through interior exit stairways and ramps are
prohibited except for equipment and ductwork necessary for independent ventilation or
pressurization, sprinkler piping, standpipes, electrical raceway for fire department communication
and security systems and electrical raceway serving the interior exit stairway and ramp and
terminating at a steel box not exceeding 16 square inches (0.010 m²). Such penetrations shall be
protected in accordance with Section 714. There shall be no penetrations or communicating
openings, whether protected or not, between adjacent interior exit stairways and ramps.
Exception: Membrane penetrations shall be permitted on the outside of the interior exit
stairway and ramp. Such penetrations shall be protected in accordance with Section 714.3.2.

It is a NEC issue but It is a stair landing not a stairway... Now fire exit stairways may be a different issue.

240.24(F) Not Located over Steps. Overcurrent devices shall not be
located over steps of a stairway.
