The Lagrangian does depend on your generalised coordinates.

Consider a particle mass m in one dimension, in a potential V=V(x).
Then
L=T-V= \frac{1}{2}m\dot{x}^{2} - V(x)

If instead of using x we used some shifted coordinate y=x+c, where c is some constant, then V=V(y-c)

L=T-V=\frac{1}{2}m\dot{y}^{2} - V(y-c)

Now notice that in general V(x) and V(y-c) are different (for example if V(x)=x).

However the equations of motion you derive from them will be equivalent. (Often choosing a clever set of coordinates makes the equations of motion easier to solve).
