✅ Safe type casting with LINQ?

As part of an octree I'm implementing, I have this line:

foreach (Leaf leaf in popped.Where(node => node is Leaf).Cast<Leaf>())

foreach (Leaf leaf in popped.Where(node => node is Leaf).Cast<Leaf>())

popped enumerates type

Node

Node

. Type

Leaf

Leaf

is a child class of

Node

Node

.
My question is, can I do this

Where

Where

and

Cast

Cast

in a single operation which is type safe or does that line look correct as-is?
