You want to use
schroot -c lenny-amd64 -- uname -a

This is a standard conventions when parsing command-line options.
The "--" option marks the end of the program options and the start
of non-option arguments (i.e. the command you want to run).  This
means that "uname" and "-a" are passed verbatim and not treated as
options at all.

This is mentioned in the Examples section of the schroot(1) manual
page.
