Tomatoes seedlings WAY too tall, can I trim tops until I can plant?

In the interim Maybe you can transplant into 1/2 gal paper milk containers. I used those one year with great success. Bury as deep as you want. Cut the container away when transplant.
Well it's been years since I did that. I always had those milk cartons handy for a leggy pepper that needed a deep planting.
I'd like to add poking a bunch of holes in the bottom of the for drainage.
