Sorry, no, the results are not identical. When we write the scale factor for a coasting model as a = mt, then the apparent magnitude-redshift (\mu -z) relation involves the parameter m. For details, please see the paper http://journals.aps.org/prd/abstract/10.1103/PhysRevD.65.043506
I agree this argument has some substance. Now we have both data of present expansion history and the early-universe data. But the question is, do we have to compromise a model that fits (if it so happens) the present data of present expansion history, for the sake of very early-universe data...
In 1996, the main difficulty with the publication of this coasting model was that it does not fit the decelerating present universe of `standard model'!
Sure, lot of details are to be worked out. But the global features like the absence of cosmological problems, such as the coincidence problem...
Thank you for your welcome. And thank you for the links to other threads in PF.

That's a wild...
In the past few months, there appear some observational results supporting the linear coasting models for the universe.
