Not in this case; the indexing in the call to 'base is executed immediately during instantiation.

You could do it this way:
public class MyClass<T1, T2, T3, T4>
{
    public T1 Value1 { get; set; }
    public T2 Value2 { get; set; }
    public T3 Value3 { get; set; }
    public T4 Value4 { get; set; }

    public MyClass(T1 value1, T2 value2, T3 value3, T4 value4)
    {
        Value1 = value1;
        Value2 = value2;
        Value3 = value3;
        Value4 = value4;
    }

    protected MyClass()
    {
    }
}

public class MyClass<T1> : MyClass<T1, T1, T1, T1>
{
    public MyClass(params T1[] values)
    {
        if(values.Length != 4) throw new ArgumentException("requires 4 parameters");

        Value1 = values[0];
        Value2 = values[1];
        Value3 = values[2];
        Value4 = values[3];
    }
}
But, look what happens: the Value properties in the base class now require a setter, and thw base class requirea a parameterless ctor.

imho, all of these implementations are hacks, and writing straightforward individual methods for each group of Types is better practice.

To me the attempt here to make these generic methods more "generalized" just leads to semantic confusion. It's not that much work to write a bunch of specific methods that can provide strict control over parameter validation, and can be unit tested efficiently.
