If you were to put 10 box fans in a straight line all facing the same direction (like dominoes); would the air coming out of the last fan be stronger than a single box fan?

I know there are probably a lot of variables to deal with here but I'm not sure what they are.

Sure, each box fan causes a pressure drop from one side to the other. The magnitude of this drop is roughly related to how much kinetic energy is imparted on the air (i.e. how fast it ends up going). 10 box fans won't cause 10 times the pressure drop of a single fan but it will certainly be fore than a single fan.
