All parameters being the same, 2 2X4s are not as strong as a 4X4 under vertical load. But there are other factors that come into play too! Quite often a 4X4 is milled from the center of the tree trunk which tends to be weaker than the sections away from the center from which 2X4 is milled. So the benefit of a higher cross sectional area may get negated. The wood grains in a 4X4 will run in one direction but the wood grains in two 2X4s could run in opposite directions. This could make 2 2X4s as strong as a 4X4. The method of joining the 2 2X4s will also play a role in how strong the bond between the two pieces is and how effective they are in functioning as a single unit.
