That does not change a thing, sorry.
The section 6 of the LGPLv2.1 is similar to the section 3 of the GPL, and mentions exactly the same limitations and exceptions for major components of the OS.

The fact that you can combine the library with a 3rd party library inside your program does not allow you to ship non-LGPL-compatible code inside the library. (The library must be changeable + redistributable by the user).

I know that means that you can do more or less the same feature, but that means the architecture must be different.
