This article describes what the maximum length of a stub line in the CAN network is.
CAN interface board, CANbridge, CAN-Repeater
The maximum length of a stub line depends on the used CAN bit rate. Lower bit rates allow to work with longer stub lines.

stub line length
Using the CAN-Repeaters the maximum CAN bus length is the line length between the two devices with the largest distance between each other. The biggest problem of the longer stubs are reflections which can distort or destroy CAN messages.
