    Yes... in the sense that any local measurement of the speed of light gives c.

    The speed of light at some location remote from the observer depends on how co-ordinates are given for space and time.

    Note that the word "local" is crucial. Also, what sylas said assumes that we're talking about a coordinate system that the standard synchronization convention associates with the world line of a moving object. If we allow arbitrary coordinate systems, the speed of light can be anything we want it to be.
