 No.
It is experimentally confirmed that the speed of light in vacuum
is invariant, which means that it is the same in all inertial
frames of reference.

 This is what all the cranks in this forum fail to understand.
Their problem is that because they find it counter intuitive
they think it can't be like that.
 But it is!

 So you think that the speed of light is frame dependent,
but can be defined to be frame independent? :-D

I meant, that 'speed of light' is actually an angle.
This angle is measured locally as velocity c.
In geometric terms it would be 45° and means the equality of two complex intervals called 'timelike' and 'spacelike'.
For any 'influence' (all sorts of interactions in a certain space with complex valued 'points', called 'spacetime') which fulfills this condition, we could use the term 'light speed'.
Now light falls into this cathegory as other em-waves, too.
Now we need to attatch an axis of time to any location and place the observer in the center of its local frame of reference, we could see, that the past light-cone of the observer is using this angle c, while the opposite means 'standstill' (actually 'relative standstill' in respect to the observer).
Now I called the comoving patters 'matter' and the inverse 'axis of time', hence matter and time are 'relative', too.
