Umm. No; Linux was not derived from Minix. Minix was a micro-kernel message-passing based system developed by Tanenbaum for education purposes (see "Operating Systems: Design and Implementation").
Linux is a traditional monolithic design with shared data structures. (Yes, early Linux used the Minix filesystem because of the early development environment used... that's the closest they came).
There is even a comparison of early Linux (0.01, 0.11 etc) to Minix where there is no similarity in the code base, on Tanenbaum's own site: http://www.cs.vu.nl/~ast/brown/codecomparison/
