I am wondering if it is possible to do the following when barreling an 1898 style Mauser action?

“A 55 degree threading tool was ground on the surface grinder with a half thread width feed side that allowed the thread to be machined to the shoulder eliminating the relief cut and allowing threads to be turned to the shoulder adding strength to this critical area.”

My first reaction is that this is a solution to a non-existent problem.

Amen to that.

Marketing (read Bullshit) drives the market. In a crowded market one must find a way for differentiation, thus create problems that don't exist. Anyone ever see a Mauser-type rifle fail because of the relief cut?

I will add that the shoulder in question is not the place where the barrel makes first contact with the receiver. The inner torque shoulder is the one that the barrel butts up hard against. The barrel may be set up to touch that receiver face (secondary torque shoulder), but the hard contact should be on the primary (inner) torque shoulder.

Pure, unadulterated, Hype, Nonsense and Bull Shit.
But to answer the OP's question; yes. But if you really wanted to do that, you should mill the threads instead of lathe single point cutting them.
But really, don't fall for it.

Now if they could eliminate the deep cuts in the extension that consist of the threads they might really have something. Until then, having a relief cut or not makes virtually no difference on structural integrity at all. It sounds an awful lot like those guys that claim to dial in uneven surfaces with a lathe cut finish to one tenth of one thousandths of an inch.

The only practical advantage to eliminating the relief cut is having the ability to pick up the threads and set the barrel back a couple of turns without lopping off the entire thread extension.

Don't feed the trolls

I like Jim Kobe and DPCD and TooManyTools when it comes to doing metal work on my rifles.

If I want to gamble, I just buy a lottery ticket.
