Yes it is possible, but isolation is a must!
People tend to trade and learn when they find they are lacking in something useful. When at least one of the two countries is xenophobic, a closed system would be formed where tech evolution takes different paths.
Take for example, the case of Japan and China in medieval times. These countries were known as curtains (bamboo curtains to be precise) and although their tech advancements were well known in the world, there was no rival research in competing countries. For example, the Chinese invented repeating crossbow (chu ko nu). Neither Japan, nor Korea or India came up with something like that. The Japanese had supreme swordmaking skills and their metalwork was (and is) regarded the best in the region. However, other countries did not try to come up with something on the same lines, but tried more to consolidate some of their other weapon technology.
However, once the barriers were lifted and world became a global village of sorts, technology from one part of the world quickly proliferated into other parts.
So yes, you can have two countries with equal in magnitude but different in direction technological progress if they are isolated and no active trade or learning is carried out between the two.
