To me it sounds highly unlikely, since Intel has spent a lot of resources in the past few years on closing the gap with AMD, and in fact is now ahead of AMD (and nVidia) in terms of features. Intel currently offers the most complete DX12-GPU on the market, supporting conservative rasterization tier 3 and raster ordered views. nVidia only supports CR tier 2 in Pascal (and CR tier 1 in Maxwell v2). AMD supports neither technology.
Their performance is close as well, and is somewhat arbitrary, since Intel generally spends less transistors on the iGPU than AMD does. So Intel should be able to just scale up the iGPU a bit if they want the same performance as AMD. Having 10 nm production can compensate somewhat for the extra transistors.
Apparently Intel doesn't think the market demands such powerful iGPUs, otherwise they would already have been offering such configurations. Instead, Intel focuses on more powerful CPUs.
I think these stories are a misinterpretation of a renewed cross-licensing of GPU technology between AMD and Intel (the 'big three' all hold a number of crucial patents on GPU technology, without which, a modern, effcient, DX12-compatible GPU would be impossible to build).
But we will see.
