Nope, you have to release the source code of the modified library, but

The difference between GPL and LGPL is that, for an LGPLed library,
its license does not require programs linked with it to be L?GPLed,
while GPL does.

It is possible to interpret the `linking' terms of the GPL in a sense
that disallows this.
