You frequently can, but remember that when you mark something as @trusted,
you're telling the compiler that you've verified that the code is
memory-safe (whereas with @safe, the compiler has verified that). So, if you
mark code with @trusted when it's not actually memory-safe, you make it so
that @safe code can call code which isn't memory-safe, and the @safe code
then isn't actually memory-safe.

So, ideally, you'd do whatever @system stuff you need to do within a
function and encapsulate the @system stuff in a way that you can mark the
function as @trusted and have an API which is memory-safe, but whether you
can do that or not depends on what your code is doing.
