I don't see any real suggestion that they'd do so. Apple has referred to their hardware in developer documentation as "Apple Silicon" -- possibly to avoid trademark issues with ARM? -- but I expect them to use the same naming scheme they use for their iOS application processors (like "Apple A16X") once they have a product ready for market. MacWorld's use of phrases like "Apple's Silicon processor" is likely to just represent confusion on the part of the journalist.
As an aside, I have a very hard time believing that Apple would reenter the networking industry. Consumer wireless access points are a commodity product at this point -- it'd be difficult for Apple to present a compelling premium option, especially when many consumers are satisfied with the one that came built into their cable modem.
