I have developed a .NET solution that consists of several assemblies, most of which are small helper assemblies that target version 2.0 of the .NET Framework. The remaining assemblies are MVC 3 Web applications, which must necessarily target version 4.0 of the .NET Framework. My solution has no other external dependencies besides the .NET and MVC Frameworks.
My question is the following: When I deploy this solution to customers, do I have to deploy both versions of the .NET Framework, or can I just deploy version 4.0? Can .NET 2.0 assemblies run under .NET 4.0?

The . NET Framework 4.5 and later versions are backward-compatible with apps that were built with earlier versions of the . NET Framework. In other words, apps and components built with previous versions will work without modification on the .
Microsoft designed the . NET Framework so that multiple versions of the framework can be installed and used at the same time. This means that there will be no conflict if multiple applications install different versions of the . NET framework on a single computer.
Yep, . NET 4.6, 4.7, 4.8, 5 and 6 can all coexist on the same machine.
The runtime always begins probing in the application's base, which can be either a URL or the application's root directory on a computer. If the referenced assembly is not found in the application base and no culture information is provided, the runtime searches any subdirectories with the assembly name.
Yes, the dependencies embedded in the assembly on .NET 2.0 assemblies are automatically translated to their 4.0 version. But it runs with a version of those assemblies it has never been tested on. They are highly compatible but contain several bug fixes, bugs that you might unknowingly have a dependency on. Nobody can give you a 100% guarantee.
Just try it.

You only need the latest version. It's downward compatible.

The answer is yes, assemblies developed for .NET 2.0 will run correctly under .NET 4.0
