Can I use a max HSE clock 24 MHz input with a 26 MHz crystal oscillator?

Hi, I'm using the STM32L152C8U6-A MCU. I want to use the high speed external clock signal (HSE). The HSE is specified for frequencies from 1-24 MHz. I have an 26 MHz crystal oscillator. What happen, if I still use the HSE with my 26 MHz crystal oscillator? Can I use the clock anyway? What are the consequences of this fix? 

 

Thank you, best regards.
