Yes, but to release the game commercial you will have to buy the full license, if you can't afford the full license and want a free 3D Modeling tool. There's Blender
What if someone makes a great model in 3ds or maya or any non free 3D program and he export this to a file format like.OBJ then import it to blender and save the file in blender format....? will this model "keep" any track/trace of the original program used to make it??? is just a quick doubt I got reading this post.
The models don't have any information of what program it is created in as it is.
But that is irrelevant, as you are still not allowed to create models in a free version of Max (or similar programs) for commercial purposes. The license isn't just for the files but mostly for using the tools.
If what you suggested even worked, it would be very illegal, as you are trying to basically scam Autodesk.
It's illegal to make anything in Max, Maya or any commercial programs (in which you have a educational license) and then to use the models you made in the program to sell, regardless of if you make it in Max or Maya or whatever and then export into blender then export to say, UDK.
I know it's ilegal but I wonder how can they know what program was used to make the model? do they ask you? I don't think so, do they go and look on your PC? I don't think so, I really think there have to be something in the model they can check like some really tiny data......
