Using a 4.0A controller to run a 4.2A stepper motor - will this be a problem?

Would there be any problems if I ran this 4.2A bipolar stepper motor...

...using this 4.0A controller via an Arduino Uno?

PWM chopper type bipolar stepper motor driver IC
1. 9V-42V DC power supply
2. H bridge bipolar constant phase flow drive
3. the maximum 4.0A of the eight kinds of output current
4. the largest 32 subdivision of the 6 models are optional
5. input signal high speed photoelectric isolation
6. common-anode standard single pulse interface
7. offline to maintain the function
8. semi closed enclosure can be adapted to a more stringent environment
9. to provide energy-saving semi-automatic current lock function
10. built-in temperature protection and over current protection.
Can control 2 phase stepper motor forward and reverse rotation, With 1-2, W1 -2 , 2W1 -2,
4W1 -2 phase excitation mode.
Only the clock pulse signal can be driven two-phase bipolar stepper motor to achieve low
vibration, high efficiency work.
IC parameter:
single chip bipolar sine microstep stepper motor driver
the new BiCD 0.13 nm process
up to 42V
resistance (a +) = 0.4
the forward and reverse rotation control
5 subdivision mode options (1/1, 1/2, 1/4, 1/8, 1/16,1/32) output current: IOUT =
4.0A (peak, in 100ms) rated
output: IOUT = 3.5 A
HZIP25 - 1.00F
input port internal pull-down resistor: 100 K
alarm output pin current:Ialert = 1mA
monitoring output pin (MO): Imo= 1mA
with reset and enable pin
with standby function
Break through the traditional, single power supply
built in overheating protection (TSD) circuit
Undervoltage protection, built-in (UVLO) circuit
built-in overcurrent detection (ISD), circuit

It's for a window auto-closer, so it will only run for a maximum of about 15 seconds, a few times a day. I don't know how much torque will be required - but using my digital luggage scales, it registered about 5kg to pull the window shut, over a distance of up to 60cm.

Both links are broken !

Maybe edit the post and use new links ?

The TB6600 is rated for a maximum of 3.5Arms, 4A peak, which actually means you can set the
amplitude upto 4A (2.8V rms). Its wise though not to run any system at its peak rating, but
derate somewhat.

Yes you can run a 4.2A motor at a lower current, it will simply have a bit less torque and be a
lot cooler.
