I will begin laying chipboard for underfloor heating in our extension. The boards are laid on joists cc60 and cc40, all joints will end up on the studs. Later, it will be leveled with 14-15mm leveling compound to reach the same level as the existing floor.
For various reasons, it would be easier for me if I do not stagger the joints in the boards.
I know that you are supposed to stagger the joints when laying drywall, but can I run into problems if I don't do it?

It depends a bit on how the flooring as a whole is dimensioned. Often, a screw-glued particleboard is included in what is needed to prevent the deformation from becoming too large. Then the cross joints should be staggered. If the floor joists themselves are sufficient, it matters less.
Greater risk of horizontal movements in joints that are on supports. Probably not a problem with a glued joint.
But why don't you install in falling lengths? It usually doesn't result in more waste.

It's not because of waste. The reasons areErik_Hansson said:
1. To make some future work steps easier, I want to wait a bit with laying the third row of boards closest to the existing house.
2. The distance is such that I can fit 3 whole 1800mm boards, so I don't have to cut the boards.
3. At the same time, I want to get rid of as much of the underfloor heating boards and joist insulation that I've already acquired.
4. Safety. Today I have a somewhat unstable temporary floor. I want a proper floor to work on as soon as possible.

You get a much stronger floor if you stagger the joints 
+ cross-brace between joists as well.
