Oddly AddRange() was my first idea for modifying your original code:

public static List<Type> GetAssemblyClasses(string assemblyName)
        {
            var assembly = Assembly.Load(assemblyName);
            List<Type> classList = new List<Type>();

            foreach (var module in assembly.GetModules())
            {
                classList.AddRange(from x in module.GetTypes().Where(x => x.IsClass) select x);
            }
            return classList;
        }
