Yes, safety matches can ignite when rubbed against a rough surface like a wall. The friction created by rubbing the match head against a rough surface can generate enough heat to ignite the chemicals on the match head, leading to a flame.
Without an atmosphere or oxygen, a match wont even spark, or even light up.

The man drops the matches in to build a fire to ignite the fuel in order to generate heat and light. The matches provide a quick and easy way to start the fire.
Matches light because the friction generated by striking them creates enough heat to ignite the chemicals on the match head. This chemical reaction produces a flame.
Without an atmosphere or oxygen, a match wont even spark, or even light up.
The purpose of rubbing two sticks together is to generate friction, which can create enough heat to ignite the sticks and start a fire. This method is a traditional way of starting fires without the need for matches or a lighter.
Phosphorus is used in matches because it is highly reactive and easily ignites when exposed to air. In matches, a small amount of phosphorus is mixed with other combustible materials to create the friction needed to ignite and produce a flame.
Assuming the sixteen matches are two squares made up of eight matches each. Two matches on top (horizontal), two matches on the bottom (horizontal), two matches on the left side (vertical), two matches on the right side (vertical). Remove one vertical match from each side from both squares. (A total of four matches) in the same row. Place two of the matches horizontally in-between the two squares both on the top and bottom. Then you'll have three squares.
Potassium chloride is used in matches as an oxidizing agent. When the match is struck, the potassium chloride reacts with the sulfur or phosphorus in the match head, creating a hot flame to ignite the matchstick.
Phosphorus is often used in matches as a component of the match head to ignite the match when struck against a rough surface. It is combined with other substances like sulfur and an oxidizing agent to create the ignition reaction.
Pyrophoricity is the property of some elements to ignite spontaneously when in contact with air or water. Two substances that ignite when brought together however, are considered hypergolic.
