Can a planet have warm or temperate climates within its polar regions?

Note: an edit has been made to the main question at the bottom

A couple of years ago, I had a worldbuilding project which I have recently revived.

I was relatively new to worldbuilding back then, and I made the terrible mistake of drawing a map of my planet before deciding axial tilt.

Now that it has been reborn, I am applying my much better worldbuilding skills to the project to give it a new and more plausible feel.

Since I already had a map of biomes, I divided the width of the page the map was on by 18 to determine lines of latitude (One for every 10 degrees).

Using the biome map, I denoted that the absolute minimum figure for the latitudes of the tropics must be 40 degrees north and south., meaning the axial tilt of the planet is 40 degrees.

Therefore, the latitudes of the polar circles would be 50 degrees north and south.

But that figure conflicts with my map. The environment only starts to change to tundra at around 20 degrees north and south, which is already halfway inside the polar circles.

So, my question is: Is it possible for the climate in the warmer half of each polar circle to be temperate, and if so, how would I do it?
