This article incorrectly states "a leaked report suggests IBM is currently investigating the possibility of moving many of its employees from Microsoft's Windows platform to Apple's popular OS."

It does not sound like IBM is internally switching to macs, as this article implies. From the original source, "Research IS is focusing on providing an IBM application stack on multiple Operating Systems, rather than be confined to one or the other." So they want their employees to know mac and have their business sell applications that run on mac to better support their customers. That doesn't sound too outrageous to me.
