No. There are monetary and performance gains for using Linux on servers and embedded products. As a result, OEMs have a financial incentive for making sure those products run Linux well. No such incentive exists for desktops.
Apple incorporates the cost of OS X into selling hardware. Windows' licenses are effectively free for OEM manufacturers.
Dell is the only major OEM I know of that offers a Linux laptop and I'd guess that division is in the red. The original Asus EEE PC was Linux only and spawned the netbook revolution, but Linux only did not last very long once the market took off and Microsoft intervened.
I believe some countries require vendors to supply the computer with an OS installed; in this case not needing to include a half-assed version of Windows Home Underwhelm Experience can help them cut away those 10% of $300 low-end models. There's a reason many netbooks come with linux and it's not user-friendliness.
Additionally, more and more governments pass laws that require their institutions to use linux or open source, or choose bidders that do. Then you have an incentive for a company which wins such a bid to use linux on umpteens of desktops.
Those are just two incentives. There are probably more.
OEMs get paid for pre-installing bloatware onto machines which can add up to $40+ per machine. Offering Linux costs them money (in addition to R&D, support, training, marketing, etc).
