No.  

Both specify an API that applications use to access OS services
and functions.  They are alternate "wrappers" for the basic
eCos kernel API.

I don't know whether it's possible to configure/use a system
that has both Posix and uITRON packages.  In theory it should
be, but there may be implimentation practicalities that prevent
it.
