✅ 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>())

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

Node

Node. Type

Leaf

Leaf

Leaf

Leaf is a child class of

Node

Node

Node

Node.
My question is, can I do this

Where

Where

Where

Where and

Cast

Cast

Cast

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